- The 404 request handler for the GCE Ingress load balancer now exports prometheus metrics, including:

  - `http_404_request_total` (the number of 404 requests handled)
  - `http_404_request_duration_ms` (the amount of time the server took to respond in ms)

- Resolves a potential issue with GC and NS controllers which may delete objects after getting a 404 response from the server during its startup. This PR ensures that requests to aggregated APIs will get 503, not 404 while the APIServiceRegistrationController hasn't finished its job.

* kube-apiserver: requests to endpoints handled by unavailable extension API servers (as indicated by an `Available` condition of `false` in the registered APIService) now return `503` errors instead of `404` errors.
