   @tillrohrmann I have the same concern before implement this PR. But now I 
think this change makes sense since Flink client will not retrieve the result 
in the application mode. BTW the per-job mode is not supported for native K8s 
integration and we do not have a plan to support per-job mode.
   
   The benefit of not resolving the rest endpoint address is we could deploy 
the Flink session/application cluster with `ClusterIP` out of the K8s cluster.
   
   The limitation is that `flink list/cancel` could not be used to contact with 
the cluster. It will fail with `TimeoutException` instead of 
`UnknownHostException `.
