In previous implementation node blocked any operation of local object
storage in maintenance mode. There is a need to perform some storage
operations like data evacuation or restoration.
Do not call block storage engine in maintenance mode. Make all Object
service operations to return `apistatus.NodeUnderMaintenance` error from
each local op.

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.

After recent changes network configuration stored in the Netmap contract
of the NeoFS Sidechain contains `MaintenanceModeAllowed` flag. There is
a need to support this value in Storage node application.
Make `NetmapService.NetworkInfo` RPC server of the storage node to set
`MaintenanceModeAllowed` flag according to corresponding value in the
Sidechain.

`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.

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.

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.

1. Do not require a request to be signed by the container owner if a
bearer token is missing
2. Do not check the system role since public requests are not expected to
be signed by IR or a container node (unlike the object requests)

There is a need to have the ability to track NeoFS timeline on storage
nodes. Epochs tick on notifications receipt, so the most obvious way to
know about received epochs is logging the events.
Wrap `morphEvent.ParseNewEpoch` event parser into function which writes
log message about new epoch number.

If container listing cache on node's side is missing (for particular
owner), then updating it as a reaction to successful container creation
leads to potentially invalid cache value for a period of time equivalent
to cache TTL.
Immediately return from `ttlContainerLister.update` method if owner's
container list isn't cached.

From now cache TTL can be parameterized in the `neofs-node` app using
`cache_ttl` config key. `disable_cache` value is no longer supported.

In previous implementation storage node responded with the outdated
container list after successful creation/removal up until cache
invalidation due to TTL. In order to decrease the probability of
outdated responses node should update its cache on event receipts.
Implement `ttlContainerLister.update` method which actualizes cached
list of the owner's containers. Make node to call `update` method
on `PutSuccess`/`DeleteSuccess` notifications from the `Container`
contract.

In previous implementation storage node responded with the removed
container up until cache invalidation due to TTL. In order to avoid
false-positive responses node should update its cache on `DeleteSuccess`
events.
Make node to call `handleRemoval` method of the container cache which
leads to subsequent `apistatus.ErrContainerNotFound` errors.

In previous implementation failed requests to the Sidechain weren't
cached. It makes sense to cache errors along with the values in order to
decrease potential load spikes onto Sidechain nodes.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
There is a need to sync container-related caching mechanism with the
actual Sidechain changes. To do this, node should be able to listen
incoming notifications about container ops.
Define `PutSuccess` / `DeleteSuccess` notification event's parsers.
Subscribe to these events in node app. As initial implementation node
will log event receipts. Later handling is going to be practically
complicated.

Modifying operations in this mode can lead node into an inconsistent state
