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

Description=Ceph cluster manager daemon
systemd/ceph-mgr: remove automagic mgr creation hack For kraken we auto-created mgr daemons next to mon daemons with some systemd hackery. This is awkward (you can't not get a new mgr daemon when you deploy a mon), systemd-specific (not implemented for upstart on trusty), and mostly unexpected. Since ceph-mgr daemons are now first-class citizens and required for every cluster, make their deployment explicit and transparent to the administrator. Major upgrades are a rare opportunity to have the administrator's full attention so take advantage of it. This effectively reverts 61d779345e9efbe9a2e3f215af1f1dcf6630f04a and 082199f69dd0bd4c18a5f4baea67a88782586657 (and follow-on fixes).

systemd: Support Graceful Reboot for AIO Node Ceph AIO installation with single/multiple node is not friendly for loopback mount, especially always get deadlock issue during graceful system reboot. We already have `rbdmap.service` with graceful system reboot friendly as below: [Unit] After=network-online.target Before=remote-fs-pre.target Wants=network-online.target remote-fs-pre.target [Service] ExecStart=/usr/bin/rbdmap map ExecReload=/usr/bin/rbdmap map ExecStop=/usr/bin/rbdmap unmap-all This PR introduce: - `ceph-mon.target`: Ensure startup after `network-online.target` and before `remote-fs-pre.target` - `ceph-*.target`: Ensure startup after `ceph-mon.target` and before `remote-fs-pre.target` - `rbdmap.service`: Once all `_netdev` get unmount by `remote-fs.target`, ensure unmap all RBD BEFORE any Ceph components under `ceph.target` get stopped during shutdown The logic is concept proof by <https://github.com/alvistack/ansible-role-ceph_common/tree/develop>; also works as expected with Ceph + Kubernetes deployment by <https://github.com/alvistack/ansible-collection-kubernetes/tree/develop>. No more deadlock happened during graceful system reboot, both AIO single/multiple no de with loopback mount.

Restart=on-failure
systemd: Wait 10 seconds before restarting ceph-mgr We do this for the MON and OSD as well, wait for a few seconds before we try to attempt a restart. On boot in IPv6 networks it might take a few seconds longer before a IP-address is usable and this does not allow the mgr to start right away.
