Feature #20606: mds: improve usability of cluster rank manipulation and setting cluster up/down
MDSMonitor: change "mds deactivate" to clearer "mds rejoin"
Rename `ceph mds deactivate` to `ceph mds rejoin`. This makes it clear an MDS is leaving and then rejoining the metadata cluster. It is not "deactivating" which to me means shutting down gently and not coming back. Running rejoin on a rank which will not result in the cluster shrinking (because max_mds has not changed) is now okay.

Agreed on "rejoin".
Okay so after a jog and some light thought, I would suggest "release" (i.e. the rank is released) or "flush" (i.e. the rank's session/journal is flushed).
In any case, this sub-ticket of #20606 interests me least so if no one thinks this is really worth changing, I'll close this.

I don't find deactivate so bad since this commands primarily deals with ranks (that just happened to be backed by a certain mds) iiuc. So if I'm not totally mistaken I think deactivate could stay and a doc change would suffice. I was actually about to propose this change.
