    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.
