Setting `.spec.endpointTrafficPolicy=Local` disables node's ability to redirect NodePort traffic to other nodes when no endpoint of that NodePort Service exists on the target node. This means that LoadBalancer Services need to be smart and only direct traffic to nodes that host the endpoint pods. This is normally achieved by using endpoint healthchecks. This commit adds a note that it is required to enable "health monitors" support in OpenStack cloud-provider configuration in order to support `ETP=Local` Services. As OVN Octavia provider in OSP16 does not support health monitors, a note is added that `ETP=Local` Services will not function properly with OVN Octavia provider. Also for ingresses with `endpointPublishingStrategy=LoadBalancerService` the created Service will have `ETP=Local` configured. This commit also adds a note to the ingress operator docs that informs that in OpenStack additional configuration of the cloud provider is required to support such Services.
