This PR includes two fixes for issues I ran into when stress testing the API. Both are technically around kops-controller going into crashloop, preventing more api servers to join the cluster. See the individual commits for details.

  • Make kops-controller use the local apiserver
  • Make APIServer role less dependent on kops-controller

API servers also have access to secret store, so there is no need to go through kops-controller.
This lets API server only depend on etcd from the CP nodes, which should make it easier to scale out API servers under pressure

If the cluster is under pressure, especially the new api server nodes, kops-controller go into crash loops because kubernetes.default doesn't respond.
By using the local api server, it has a higher likelyhood of being able to connect.
