This change moves the ceph-mgr deployment from the ceph-client
chart to the ceph-mon chart. Its purpose is to facilitate the
proper Ceph upgrade procedure, which prescribes restarting mgr
daemons before mon daemons.
There will be additional work required to implement the correct
daemon restart procedure for upgrades. This change only addresses
the move of the ceph-mgr deployment.
