This PS moves to namespace specific ingress controllers, and a cluster wide ingress controller that acts as the external front door to the cluster. The cluster ingress controller will also be able to create a dummy interface that can be announced via the OpenStack-Helm-Infra Calico chart. The ability to exercise the edge VIP feature is currently only demonstrated in the single node gate and guide, as it requires additional configuration, or hardware to set up the routes in a multinode env.
