[#1680] morph/netmap: Allow to set MAINTENANCE state
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. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
