[#1797] node/control: Verify states in SetNetmapStatus RPC server

Browse source 
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.
