Deploy kubelet and kube-apiserver as containers kubelet via docker kube-apiserver as a static pod Fixed etcd service start to be more tolerant of slow start. Workaround for kube_version to stay in download role, but not download an files by creating a new "nothing" download entry.

Copy kubectl from docker container Nearly the last stage of source all components to containers. Kubectl will be called from hyperkube image. Remaining tasks: * Move kube_version variable to kubernetes/preinstall * Drop placeholder download.nothing requirement
