In upgrade_ovn_dbs, I'd consider upgrading both databases even if they
don't appear in the list of databases.  It seems more robust to me,
especially given this comment in start_northd:

 # We expect ovn-northd to be co-located with ovsdb-server handling both the
 # OVN_Northbound and OVN_Southbound dbs.

I'm not sure about error handling.  If an upgrade to one database fails,
it might be better to try to upgrade the other database instead of
exiting immediately.
