* related to: * https://github.com/kubernetes/ingress-nginx/issues/3070 * https://github.com/kubernetes/ingress-nginx/issues/3335 * add a 503 test * test a service that starts out empty (a.k.a. ingress-nginx controller (re-)start) * test scaling up (should route traffic accordingly) * test scaling down to empty service * use custom deployments for scaling test. * provide a fix by updating the lua table (cache) of the configured backends to unset the backend if there are no endpoints available.
