Currently, we start/stop OSDs and MONs simultaneously. This may cause
problems especially when we are shutting down the system. Once the mon
goes down it causes a re-election and the MONs can miss the message
from the OSD that is going down.

This looks good to me, but I'll leave it open to make sure we didn't bust those unit tests and in case anybody else with more systemd experience wants to comment.

Tracker issue has empty backport field, so this is master-only until that changes, JFYI
