After recent Netmap contract changes all read methods which return
network map (either candidates or snapshots) encode node descriptors
into same structure.
Decode `netmap.Node` contract-side structure from the call results.
Replace node state with the value from the `netmap.Node.State` field.

Make storage node to return `NODE_UNDER_MAINTENANCE` status
error on each local object operation if the node is in `MAINTENANCE`
mode.
Pass `apistatus.NodeUnderMaintenance` to `StorageEngine.BlockExecution`
during `ControlService.SetNetmapStatus` RPC processing.

After recent changes `MAINTENANCE` state is reflected in the Sidechain.
Storage node should switch its state to "maintenance" during serving the
`ControlService.SetNetmapStatus` RPC with correspoding status in the
request.
Call `UpdatePeerState` operation of Netmap contract's client in
`control.NodeState` provider on Storage node app side. The op is
executed if `BlockExecution` on local object storage is succeeded.

Storage node can be requested to be switched into `MAINTENANCE` state.
Inner Ring should accept such requests only if network configuration
allows it.
Make `Processor` of Netmap contract's notifications to depend on
`state.NetworkSettings`. Make `Processor.processUpdatePeer` to call
`MaintenanceModeAllowed` if notification event relates to `MAINTENANCE`
mode`. Share singe `state.NetworkSettings` provider in Inner Ring
application.

After recent changes Netmap contract can send `UpdateState` notification
event with `MAINTENANCE` node's state. There is a need to provide
functionality to work with the status.

`ParseUpdatePeer` and `ParseUpdatePeerNotary` functions.

After recent changes in NeoFS protocol storage nodes can be in
`MAINTENANCE` state. There is a need to support this state in
`UpdateState` operation.
Add `UpdatePeerPrm.SetMaintenance` method which makes node to be
switched into `MAINTENANCE` mode after the `UpdatePeerState` operation.
New functionality is going to be used in Storage node application for
Control API serving.

Inner Ring should allow registering of storage nodes with `MAINTENANCE`
state in the NeoFS network only if its configuration allows this status.
Make `networkSettings.MaintenanceModeAllowed` to call
`MaintenanceModeAllowed` method of underlying Netmap contract's client
in order to assert state allowance.
From now nodes will be accepted to the network with `MAINTENANCE` state
only with the appropriate network configuration.

After recent changes network configuration stored in the Netmap contract
of the NeoFS Sidechain contains `MaintenanceModeAllowed` flag. There is

After recent changes in the NeoFS API protocol network configuration
contains `MaintenanceModeAllowed` boolean flag. There is a need to
support the config value in all NeoFS applications.
Provide `Client.MaintenanceModeAllowed` method which read the config
from the Sidechain. Extend `NetworkConfiguration` structure with
`MaintenanceModeAllowed` field.

`NetworkConfiguration` represents NeoFS network configuration stored in
the Sidechain. In previous implementation the configuration missed flag
of disabled homomorphic hashing.
Add `NetworkConfiguration.HomomorphicHashingDisabled` boolean field.
Decode the field in `Client.ReadNetworkConfiguration` method. Print this
value in `netmap netinfo` command of NeoFS CLI.

`readBoolConfig` method is going to be reused for reading other
configuration values. All boolean settings are `false` by default, so it
makes sense to return default value on missing key directly from
`readBoolConfig`.
Handle `ErrConfigNotFound` case in `readBoolConfig` method. Change
`HomomorphicHashDisabled` method to call `readBoolConfig` directly.

There is a need to prevent limitless abuse of MAINTENANCE status of the
storage nodes. To do this, configuration of the NeoFS network is going
to be extended with the flag which allows the state. Until this is done,
it makes sense to prepare a site for this in the code.
Define `state.NetworkSettings` interface as an abstraction of global
network configuration within the `state` package. Make
`NetMapCandidateValidator` to depend on `NetworkSettings` and provide
corresponding field setter. Change `VerifyAndUpdate` method's behavior
to return an error for candidates with MAINTENANCE state if this state
is disallowed by the network configuration. Provide `NetworkSettings`
from the wrapper over Netmap contract's client on Inner Ring application
side. The provider is implemented to statically disallow MAINTENANCE
mode in order to save previous behavior.

New network status of storage nodes is going to be introduced. To

In previous implementation storage node interpreted all status values
sent in `SetNetmapStatus` RPC as `OFFLINE` except `ONLINE` and
`MAINTENANCE`. This could lead to incorrect processing of new values,
and also didn't allow detection of problems with sending garbage values.
Make implementation of `NodeState` interface used by Control API server
to deny requests with statuses other than protocol-declared enum.

In previous implementation Inner Ring allowed storage nodes with any
state to register in the network. According to the current design, only
nodes with ONLINE state are allowed to enter the network map.
Create new `state` sub-package of `nodevalidation` package of Inner Ring
application. Define `state.NetMapCandidateValidator` type and provide
`NodeValidator` interface required by the Inner Ring's processor of
`Netmap` contract's notification events. Embed new validator into the
one used by the Inner Ring application.
From now all `AddPeer` notifications with node state other than `ONLINE`
will be denied.

Allow user to initiate flushing objects from a writecache.
We need this in 2 cases:
1. During writecache storage schema update, it should be flushed with
the old version of node and started clean with a new one.

Replace `ProcessCurrentNetMap` method of `NodeState` interface with
`ReadCurrentNetMap` one with two changes:
* Replace network map type from NeoFS SDK package with the
protocol-generated message. This replaces all the business logic to
the application layer.
* Support error return. This allows to cover problem node states.
Return an error from `NodeState.ReadCurrentNetMap` method implemeted
through `atomic.Value` if `Store` method has not been called yet.
