[#62 ] morph: List morph rules chains by traversing iterator

* Make `ListMorphRuleChains` methods use `commonclient.ReadIteratorItems`. * Introduce `ContractStorageActor` interface. * Iterators are used because listing by `ListChainsByPrefix` may cause stack overflow from neo-go side (len(items) > 1024). Signed-off-by: Airat Arifullin <aarifullin@yadro.com>

-# Access policy engine
-
-## General overview
-
-### Purpose
-
-Access policy engine (APE) is aimed at checking if a request can be performed over a resource by looking up the set chains of rules.
-
-#### Terms
-
-| Term           | Description                                                    | Structure overview     |
-| -------------- | -------------------------------------------------------------- | -------------- |
-| `Request`      | The action that is being performed on the `Resource`.                          | <ul><li>`Operation` - `GetObject`,`PutObject` etc.;</li><li>`Properties` - actor's public key, actor's attributes;</li><li>`Resource`.</li></ul> |
-| `Resource`     | The object that the request is being performed on. Check also [resource.md](./resource.md).   |  <ul><li>`Name` - strictly formatted string value;</li><li>`Properties`.</li></ul> |
-| `Chain`        | A chain of `Rule`-s defined for a specific target. Chains are strictly distinguished by `Name`-s , i.e. chains with name `ingress` are not intersected with chains with name `s3`. Chains are stored in serialized format.       | <ul><li>Base64-encoded `ID`;</li><li>List of `Rule`-s;</li><li>`MatchType` - defines rule status selection priority.</li></ul> |
-| `Rule`         | `Rule` defines which status is returned if `Request` matches all conditions.                                                         | <ul><li>`Status`: `Allow`, `AccessDenied`, `QuotaLimitReached`, `NoRuleFound`;</li><li>`Actions` - operation defined by a schema (`GetObject`, `PutContainer` etc.);</li><li>`Resources`;</li><li>`Any` - if `true` then `Reqeust` matches `Rule` if any `Condition` is `true`;</li><li>`Conditions`.</li></ul> |
-| `Name`   | `Name` of a chain (do not confuse with chain ID). `Name` defines a layer of `Chain`'s usage, so chains are distinguished by `Name`-s. Basically, `Name` refers to a protocol.                                                       | String value (`ingress`, `s3`, `iam`).      |
-| `Target`       | A scope of request. `Target` can be either simple (only namespace; only container; only user; only groups) or compound (namespace + container). | <ul><li>`Namespace`;</li><li>`Container`;</li><li>`User`;</li><li>`Groups`.</li></ul> |
-| `Engine`       | `Engine` checks a request in a scope defined by `Target`. First, it is trying to match a request with rules defined in `LocalOverrideStorage` and, then, in `MorphRuleChainStorage`.                                                          | <ul><li>`LocalOverrideStorage` - chains stored in the local override storage have the highest priority</li><li>`MorphRuleChainStorage` - basically, chains stored in `Policy` contract;</li><li>`ChainRouter` - looks up chains and try to match them with `Request`.</li></ul> |
-
-#### Details
-
-Here some entities are overviewed in more detail.
-
-##### Resource
-
-`Resource`'s name is strictly formatted, the format is defined by a schema (`native`, `aws` etc.). Examples:
-
-```bash
-# The resource is the particular object with the address within Root namespace
-native:object//HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/EbxzAdz5LB4uqxuz6crWKAumBNtZyK2rKsqQP7TdZvwr
-# The resource is all objects within the container within Root namespace
-native:object//HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/*
-# The resource is the particular container within the namespace
-native:container/namespace1/HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj
-# The resource is all containers within the namespace
-native:container/namespace1/*
-```
-
-##### Rule
-
-`Rule` works out if:
-
- 1. a requests's operation matches the rule's `Actions`;
- 2. resource name matches the rule's `Resources`;
- 3. if all (or at least one if `Any=true`) conditions in `Condition` is met. Each condition defines how to retrieve
-and compare the retrieved value. If `Condition`'s `Object` is set to `Resource` then the value is retrieved from the
-resource's properties (example: container zone attribute). If `Object` is set to `Request`, the it's retrieved from the request's properties (example: actor's public key).
-
-###### Name matching
-
-`Resource`'s name in `Rule` may contain wildcard '*' that can be considered as a regular expression:
-
-```bash
-# The resource is all objects within the container within Root namespace
-native:object//HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/*
-```
-
-If an incoming request has such a resource name, then names are matched:
-
-```bash
-# The resource is all objects within the container within Root namespace
-native:object//HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/EbxzAdz5LB4uqxuz6crWKAumBNtZyK2rKsqQP7TdZvwr
-```
-
-If the incoming request has such a resource name that specifies a container's object within namespace, for instance, `namespicy`,
-then matching does not work out:
-
-```bash
-# The resource is all objects within the container within `namespicy` namespace:
-native:object/namespicy/HRwWbb1bJjRms33kkA21hy4JdPfARaH3fW9NfuNN6Fgj/EbxzAdz5LB4uqxuz6crWKAumBNtZyK2rKsqQP7TdZvwr
-```
-
-##### Engine
-
-`Engine` is trying to match the request against **the target** looking up chain rules, firstly, in `LocalOverrideStorage` (these rules are also known as *local overrides*) and then in `MorphRuleChainStorage` (contract `Policy`). Both storages iterate chain rules according to the specified priority of the targets: `namespace` -> `container` -> `user` -> `groups`.
-
-#### Diagrams
-
-The diagram demonstrates a scenario in Storage node. The request `A` cannot be performed as APE matched
-the request and returned `Access Denied` status. The request `B` is allowed and the client gets `OK` status.

-The diagram demonstrates a complex scenario with S3, IAM and Storage node.

-# Policy converters
-
-This repository contains converters that provide opportunities to
-transform [AWS IAM policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies.html) to inner
-FrostFS policy format. This document describes such transformations.
-
-## FrostFS
-
-As it was mentioned there are converters that transform AWS IAM policies to FrostFS.
-Here common examples of AWS:
-
-```json
-{
-  "Version": "2012-10-17",
-  "Statement": [
-    {
-      "Effect": "Allow",
-      "Action": [
-        "s3:*"
-      ],
-      "Resource": "*"
-    }
-  ]
-}
-```
-
-and FrostFS:
-
-```json
-{
-  "ID": "c29tZS1pZA==",
-  "Rules": [
-    {
-      "Status": "Allow",
-      "Actions": {
-        "Inverted": false,
-        "Names": [
-          "s3:*"
-        ]
-      },
-      "Resources": {
-        "Inverted": false,
-        "Names": [
-          "*"
-        ]
-      },
-      "Any": false,
-      "Condition": null
-    }
-  ],
-  "MatchType": "DenyPriority"
-}
-```
-
-policies.
-
-Despite there is only one FrostFS format, we have two converters (`s3` and `native`). The reason is S3 gateway and
-Storage node have different actions and resource naming:
-
-* S3 has [a lot of methods](https://docs.aws.amazon.com/AmazonS3/latest/API/API_Operations.html) and operates with
-  bucket/object
-* Storage node has only 6 container and 7 object methods and operates container/object (that has different format)
-
-The following sections describe each transformation more precisely ([common](#common) sections contains shared concepts)
-
-### Common

-#### Fields
-
-Rough json main fields mapping:
-
-| AWS policy field | FrostFS policy field | Comment                                                          |
-|------------------|----------------------|------------------------------------------------------------------|
-| `Version`        | -                    | Not applicable                                                   |
-| `Statement`      | `Rules`              |                                                                  |
-| `Effect`         | `Status`             |                                                                  |
-| `Action`         | `Actions.Names`      | `Actions.Inverted` = false                                       |
-| `NotAction`      | `Actions.Names`      | `Actions.Inverted` = true                                        |
-| `Resource`       | `Resources.Names`    | `Resources.Inverted` = false                                     |
-| `NotResource`    | `Resources.Names`    | `Resources.Inverted` = true                                      |
-| `Condition`      | `Condition`          | `Any` = false, that means the conditions must be hold altogether |
-| `Principal`      | -                    | Expressed via conditions (depends on s3/native converters)       |
-
-### Conditions
-
-Each condition in FrostFS policy can add requirements to some request/resource properties
-and consists of the following fields:
-
-| Field    | Description                                                                               |

-| `Op`     | Condition type operation (`StringEqual`, `NumericEqual` etc)                              |                                                                   
-| `Object` | Property type to which condition can be applied (`Request` property, `Resource` property) |                                                                   
-| `Key`    | Property key                                                                              |                                                                   
-| `Value`  | Property value                                                                            |

-### S3
-
-#### Actions
-
-Each action allows some s3-gw methods, so we must transform action to specific method names
-(you can see exact mapping in table in [this file](../iam/converter_s3.go)).
-
-For example the following actions:
-
-```json
-{
-  "Action": [
-    "s3:DeleteObject",
-    "iam:CreateUser"
-  ]
-}
-```
-
-transforms to
-
-```json
-{
-  "Actions": {
-    "Inverted": false,
-    "Names": [
-      "s3:DeleteObject",
-      "s3:DeleteMultipleObjects",
-      "iam:CreateUser"
-    ]
-  }
-}
-```
-
-As we can see any `iam:*` action transformed as it is. But `s3:*` actions transforms according to
-[spec rules](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazons3.html) and s3-gw
-[method names](https://git.frostfs.info/TrueCloudLab/frostfs-s3-gw/src/commit/2ab655b909c40db6f7a4e41e07d8b99167f791bd/api/middleware/constants.go#L3-L76).
-
-#### Resources
-
-Resource is transformed as it is:
-
-```json
-{
-  "Resource": [
-    "arn:aws:s3:::bucket/object"
-  ]
-}
-```
-
-```json
-{
-  "Resources": {
-    "Inverted": false,
-    "Names": [
-      "arn:aws:s3:::bucket/object"
-    ]
-  }
-}
-```
-
-#### Principals
-
-To check user s3-gw uses special condition request property (`Owner`), so when AWS policy contains principal field
-it transforms to rule with appropriate condition. To get correct `Owner` property value special user resolver
-(`S3Resolver` interface in [converter_s3 file](../iam/converter_s3.go)) must be provided into convert function.
-
-For example such AWS json statement:
-
-```json
-{
-  "Effect": "Allow",
-  "Action": "*",
-  "Resource": "*",
-  "Principal": {
-    "AWS": "arn:aws:iam::111122223333:user/JohnDoe"
-  }
-}
-```
-
-transforms to the following FrostFS rule:
-
-```json
-{
-  "Status": "Allow",
-  "Actions": {
-    "Inverted": false,
-    "Names": [
-      "*"
-    ]
-  },
-  "Resources": {
-    "Inverted": false,
-    "Names": [
-      "*"
-    ]
-  },
-  "Any": false,
-  "Condition": [
-    {
-      "Op": "StringEquals",
-      "Object": "Request",
-      "Key": "Owner",
-      "Value": "NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM"
-    }
-  ]
-}
-```
-
-### Native
-
-#### Actions
-
-Each action allows some frostfs methods, so we must transform action to specific method names
-(you can see exact mapping in table in [this file](../iam/converter_native.go)).
-
-For example the following actions:
-
-```json
-{
-  "Action": [
-    "s3:DeleteObject",
-    "iam:CreateUser"
-  ]
-}
-```
-
-transforms to
-
-```json
-{
-  "Actions": {
-    "Inverted": false,
-    "Names": [
-      "PutObject",
-      "HeadObject",
-      "GetObject",
-      "RangeObject",
-      "GetContainer",
-      "DeleteObject"
-    ]
-  }
-}
-```
-
-> **Note:** Only subset of s3:* actions can be transformed (exact value you can see in mapping table mentioned before).
-> If all provided actions is not applicable converter function returns appropriate error.
-
-Native methods (to which original actions are transformed) depend on which methods are invoked by appropriate s3-gw
-[method](https://git.frostfs.info/TrueCloudLab/frostfs-s3-gw/src/commit/2ab655b909c40db6f7a4e41e07d8b99167f791bd/api/middleware/constants.go#L3-L76).
-
-So in example above s3-gw during performing DeleteObject methods invokes the following methods:
-`["PutObject","HeadObject","GetObject","RangeObject","GetContainer","DeleteObject"]`
-
-#### Resources
-
-To transform resources the following is being performed:
-
-* Bucket name is resoled to container id (by providing `NativeResolver` interface implementation to converter)
-* Object name is transformed to condition with special `FilePath` attribute
-  (that present on every object that was uploaded via s3-gw)
-
-For example, the following AWS policy statement:
-
-```json
-{
-  "Principal": "*",
-  "Effect": "Allow",
-  "Action": "*",
-  "Resource": "arn:aws:s3:::bucket/object"
-}
-```
-
-transforms to FrostFS native policy rule:
-
-```json
-{
-  "Status": "Allow",
-  "Actions": {
-    "Inverted": false,
-    "Names": [
-      "*"
-    ]
-  },
-  "Resources": {
-    "Inverted": false,
-    "Names": [
-      "native:object//bucket/HFq67qbfhFEiEL7qDXqayo3F78yAvxXSXzwSa2hKM9bH/*",
-      "native:container//bucket/HFq67qbfhFEiEL7qDXqayo3F78yAvxXSXzwSa2hKM9bH"
-    ]
-  },
-  "Any": false,
-  "Condition": [
-    {
-      "Op": "StringLike",
-      "Object": "Resource",
-      "Key": "FilePath",
-      "Value": "object"
-    }
-  ]
-}
-```
-
-#### Principals
-
-To check user s3-gw uses special condition request property (`$Actor:publicKey`), so when AWS policy contains principal
-field it transforms to rule with appropriate condition. To get correct `$Actor:publicKey` property value
-special user resolver (`NativeResolver` interface in [converter_native file](../iam/converter_native.go)) must be
-provided into convert function.
-
-For example such AWS json statement:
-
-```json
-{
-  "Effect": "Allow",
-  "Action": "*",
-  "Resource": "*",
-  "Principal": {
-    "AWS": "arn:aws:iam::111122223333:user/JohnDoe"
-  }
-}

-    "Inverted": false,

-      "native:object/*",
-      "native:container/*"
-    ]

-    {
-      "Op": "StringEquals",
-      "Object": "Request",
-      "Key": "$Actor:publicKey",
