The change this pulls in ensures that when service_resume is called (which
happens on every update-status hook), services are only enabled and started if
they are disabled and stopped respectively.
Also pins charmcraft to 2.2/stable since 2.5.5 throws an error building charmtools.
The OVN charms prepared for the upgrade from OVN 20.03 to newer
versions by enabling the version pinning by default.
Since then we have reached agreement with upstream that rolling
upgrades should work when upgrading within the previous upstream
LTS version and the next.
Having the pinning enabled by default causes unnecessary grief for
anyone already upgraded to OVN 22.03, so it's time to turn it off
by default.
We add a charm configuration option in case anyone wants to
upgrade across LTS boundaries in the future.
