[Bug 1646583] Re: Ceph mon doesn't restart on reboot with Xenial when using ceph-{mon, osd}@ systemd units

I installed Ceph from the SRU PPA using Ceph ansible and while the ceph-
mon target file is there the Ceph monitor does not auto-start on reboot.
I've installed 10.2.5 from ceph.com apt repo simply using apt-get install and these are the units listed:
# systemctl list-units | grep ceph
ceph-mds.target
ceph-mon.target
ceph-osd.target
ceph.target
I believe the units after an apt install of the Canonical package do not match this. I'm pretty sure the ceph-mon.target and ceph-osd.targets are missing but I don't have a clean system to test this on at the moment. I'll update again later today after I try it out.

This is likely caused by the same clash between upstream target files
and Ubuntu systemd unit files that is noted in [1] but I have opened a
separate bug because I believe the severity of not having Ceph restart
automatically on server reboot is higher severity than not being able
to start/stop all services with one command, which is what is reported
in [1].
The source of the Ubuntu package [2] does not have the necessary
target files that upstream Ceph added to allow for restart on reboot
under this commit [3] which is included in Ceph's github tag 10.2.2.
