We still get the UDP Port 8080 not found on Service default/service-1 message in the ResolvedRefs condition.

For HTTPRoute, we generate a route with a 500 direct response for routes with failed backends. However, there's no similar mechanism for UDP/TCP/TLS Route.

Add a test in the xDS - it'll generate a cluster without endpoints.
