This patch ensures devstack deploys the K8s API behind an L3 amphora driver based loadbalancer, since OVN may not work properly in case L2 mode is selected. In addition, it drops the load balancer cascade deleting differences for ovn-octavia provider, as this is being fixed on ovn side. Depends-On: I31da7134d51665bbfe316b8a05cc34216420a4d0 Implements: blueprint octavia-ovn-provider Change-Id: I89e969ae52378a7c62ac552e1a69b7e2a45bd23a
