In previous implementation node lost maintenance status after successful
switching to it. For example, after some period of time node sent
bootstrap requests with the "online" state instead of "maintenance".
Make `startMaintenance` method to set maintenance status in the
`networkState`.

In previous implementation bootstrapping state was chosen according to
bool flag which was not convenient.

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.

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

each local op.

Make storage node to return `NODE_UNDER_MAINTENANCE` status

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

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

Sidechain.

`NetworkConfiguration` represents NeoFS network configuration stored in
the Sidechain. In previous implementation the configuration missed flag

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.
