Bug description:
  [Original Description]
  I noticed that every time we have a controller reboot, the glance units (all three) return with glance-api service stopped, and the charm complains about it being stopped when it should be running.

  Entering the units and manually starting those services fixes the
  problem and the charm goes happy. After doing this a few times, I
  noticed that those glance-api services are marked as "disabled" in
  systemd, and that's why they don't come back after a reboot.

  Probably the charm should set them enabled when installing?

  [Description]
  OpenStack packages that specify debhelper (>= 10~) or debhelper-compat (= 10) do not generate a var/lib/dpkg/info/<package>.postinst script that enables the corresponding systemd service.

  For example, on impish:
  sudo apt install glance-api
  systemctl status glance-api will show that the service is disabled

  root at i1:~# systemctl status glance-api
  ● glance-api.service - OpenStack Image Service API
       Loaded: loaded (/lib/systemd/system/glance-api.service; disabled; vendor preset: enabled)
       Active: active (running) since Tue 2022-03-01 21:04:49 UTC; 1min 5s ago

  Once fixed, it will be enabled by default.

  [TestCase]
  Install any service from the affected package and it will be enabled by default once fixed.

  [Regression Potential]
  Moving to debhelper compat level 12 changes behavior as described in the man page at https://manpages.debian.org/testing/debhelper/debhelper.7.en.html#Supported_compatibility_levels. Nothing jumps out to me as a potential regression, rather there are behavioral changes, such as what fixes this bug where the generated postinst script has different behavior. Typically I would not prefer to change the compat level in an SRU unless it fixes a high impact bug, as it does in this situation. All other openstack packages that provide systemd init scripts, and are not affected by this bug, are already at compat level 12.
