    Fix the non-HA case where OVN has its own VIP

    When OVN has its own VIP, the non-HA case is currently broken.
    Tempest will fail when creating networks as neutron components
    will try to reach the OVN VIP (managed by keepalived)
    that never gets created:

    With this change we add the correct hiera key for keepalived
    to create the dedicated OVN DBS VIP.
