Bug description:
  [Impact]
  At Focal we took a stance that moving forward new deployments of Charmed OpenStack should use OVN as the SDN. For clouds upgrading, Focal is also the point for which a migration from ML2/OVS to ML2/OVN should take place before further upgrades are applied.

  The current lack of support for reverse DNS lookup for IP addresses
  belonging to project instances would prevent users with applications
  depending on this feature to commence new deployments or upgrade
  through Focal and beyond.

  [Test Plan]
  Deploy a Charmed OpenStack and perform forward and reverse DNS lookups for instance names and addresses with the old and new packages to confirm.

  [Regression Potential]
  The instance DNS resolution in OVN works by looking up records in the OVN Southbound database. The CMS adds records for both forward and reverse lookups and the OVN controller needs to know how to look for them. The included patches have been available for several upstream releases without any reported issues. In addition we have been running internal clouds with these patches without issues.

  [Original Bug Description]
  There's an upstream bug that mentions this during implementation of regular DNS lookups - https://bugzilla.redhat.com/show_bug.cgi?id=1503521
