Public bug reported: When OVN DBs are upgraded (and restarted), there might be cases whenever we want to accommodate things to a new schema. In this situation we don't want to force a restart of neutron-server (or metadata agent) but instead, detect it and run whatever is needed.
This can be achieved by checking the schema version via ovsdbapp [0] and comparing if it's bigger than what we had upon a reconnection to the OVN DBs.
