This reverts commit 6eb7f3b72b.
Reason for revert: Kubernetes service patch broke ovn-* relations
Upgrade to kubernetes_service_patch changed the way the service loadbalancer is setup. Before, it updated the application service, now it creates a new one. This broke ovn-* relations to outside the cluster because the `ingress-bound-address` is now filled with a k8s svc ip address, not reachable from the outside.
