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.

Purge legacy cleanup tasks from older than 1 year (#4450) We don't need to support upgrades from 2 year old installs, just from the last major version. Also changed most retried tasks to 1s delay instead of longer.

- name: "Pre-upgrade | Delete master containers forcefully"
Master component and kubelet container upgrade fixes * Fixes an issue where apiserver and friends (controller manager, scheduler) were prevented from restarting after manifests/secrets are changed. This occurred when a replaced kubelet doesn't reconcile new master manifests, which caused old master component versions to linger during deployment. In my case this was causing upgrades from k8s 1.6/1.7 -> k8s 1.8 to fail * Improves transitions from kubelet container to host kubelet by preventing issues where kubelet container reappeared during the deployment
