Description

Currently, cephadm allows to redeploy services as a whole which sometimes might be a little over the top if only one daemon instance ran into problems or could be critical if it's related to the redeployment of the mgr service (see Bug #49013 where all but one mgr daemon went offline).

It would be great if cephadm would allow to redeploy a single daemon of a service. The command could look like this

ceph orch daemon redeploy [DAEMON_TYPE] --host [NAME]

or this
ceph orch daemon redeploy [DAEMON_TYPE].[HOST]
