ceph: services: judge the OSD map flags only for OSD restarts

The OSDMAP_FLAGS check applied to every daemon type. An operator who
set nodown to stop OSDs from flapping could then not restart the
monitors either. Every flag in the OSD map controls OSD behaviour
only. None of them affects monitor quorum, manager failover or MDS
takeover, so refusing those restarts was wrong.

For OSDs the check still matters. nodown keeps every OSD marked as up,
so the wait for a restarted OSD returns immediately. A caller that
does not name a daemon type is still judged strictly. nosnaptrim and
noautoscale count as benign now too, because neither affects a daemon
restart.
