By default writecache puts the whole object to update storage ID.
This logic comes from the times when we needed to put objects
in the metabase by the writecache itself. Now this is done by the
blobstor at unmarshaling objects during flush only to update storage ID
is an overkill.

In previous implementation `Shard.Delete` logged writecache's removal
failures in `error` level. There is a need to decrease severity of these
log records since they aren't critical and don't require individual
review.

In previous implementation turning to maintenance mode using NeoFS CLI
required NeoFS API endpoint. This was not convenient from the user
perspective. It's worth to move networks settings' check to the server
side.
Add `force_maintenance` field to `SetNetmapStatusRequest.Body` message
of Control API. Add `force` flag to `neofs-cli control set-status`
command which sets corresponding field in the requests body if status is
`maintenance`. Force flag is ignored for any other status.

Storage node should not provide NeoFS Object API service when it is

In previous implementation `ObjectService.Get` RPC handler failed with
`parent address in child object differs` while assembling the "big"
object. This was caused by the child check which required parent
reference to be set in all child objects. The check was impracticable
because not all elements of the split-chain have a link to the parent.

parent header in its own header.

Node response with `NODE_UNDER_MAINTENANCE` status signals that the node
was switched to maintenance mode. There is a delay between the actual
switch and the reflection in the network map of up to one epoch. To

such node responses in the Policer.

Nodes under maintenance SHOULD not respond to object requests. Based on

In previous implementation of `neofs-node` app object session was not
checked for substitution of the object related to it. Also, for access
checks, the session object was substituted instead of the one from the
request. This, on the one hand, made it possible to inherit the session
from the parent object for authorization for certain actions. On the
other hand, it covered the mentioned object substitution, which is a
critical vulnerability.
Next changes are applied to processing of all Object service requests:
- check if object session relates to the requested object
- use requested object in access checks.

network configuration within the `state` package. Make

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`
