Comment 8 for bug 1863510

Some points to remember (as discussed during meeting):
1) the issue is in looping with notify - don't rely on it solely
2) there could be performance issues with include_tasks at scale
3) there is also an issue that interrupted deploy/reconfigure may *not* restart containers if it failed between config update and planned restart (due to no change happening later)
  3a) we could do some touch dance
  3b) "kolla_set_configs --check" or similar
4) at some point in time we might want to switch to podman which relies on systemd (no idea how it affects this but nice to remember)
