systemd: add ceph-mgr service and target files Signed-off-by: Tim Serong <tserong@suse.com>

[Unit]
Description=Ceph cluster manager daemon
systemd: encourage ceph-mgr to start in sync with ceph-mon This change introduces the following behaviour: - When ceph-mon starts, it will try to start ceph-mgr with the same instance id (Wants=), but will *not* fail to start if ceph-mgr doesn't start (i.e. the mon still works as it always did). - ceph-mgr will start After= ceph-mon, and will stop and start when ceph-mon stops and starts, because it's PartOf= ceph-mon. If you don't want ceph-mgr to run on the mons, you need to mask the service, i.e. `systemctl mask ceph-mgr@INSTANCE`. Hostnames are typically instance names, so `systemctl mask ceph-mgr@$(hostname)` should suffice if you wish to disable ceph-mgr on the mons. Signed-off-by: Tim Serong <tserong@suse.com>

systemd: autogenerate ceph-mgr key during daemon startup This is a hack to inject a key for the mgr daemon, using whatever key already exists on the mon on this node to gain sufficient permissions to create the mgr key. Failure is ignored at every step (the '-' prefix) in case someone has already used some other trick to set everything up manually. Signed-off-by: Tim Serong <tserong@suse.com>
