Michele Baldessari 40da6ed234 OVN DBs clustering ... We introduce support for running both the NB and SB OVN databases in clustered mode. This OVN DBs clustered mode is based on OVNs own clustering protocol and does not rely on pacemaker. Clustering the two OVN databases increases reliability. The cluster works in active-active mode and has the potential to be more resilient and performant. See https://docs.openvswitch.org/en/latest/ref/ovsdb.7/#clustered-database-service-model for more information. For backport simplicity we also add I50cf3b7d79d8cd139ae514438e147df73901a366 ("Fix typo in ovn-dbs-cluster northd kolla config file") which is a cherry-pick + squash of commit 1115698c14, so we avoid ovn_northd connecting only to the local db via unix socket.
