Add static and dynamic kubelet config support

Kubelet can be configured on startup now - just add new key/values in:
kubelet-static-config.yml.j2

Also kubelet static (startup) configuration can be overriden later
(dynamically) during its runtime - for more info read this:
https://kubernetes.io/docs/tasks/administer-cluster/reconfigure-kubelet/
