Enable local-up-cluster.sh to start with the secured port

Generate a kubeconfig for use with controller-manager, kubelet,
scheduler etc. This kubeconfig should use the secure https
port of the api server with appropriate ca cert for the components
to talk to api server.

With this change, one can set API_PORT=0 to completely switch off
insecure access for testing admission controllers etc.
