The gist is that `kubelet` service code only manages the container lifecycle, while `kubelet` configuration is managed now in the controllers and resources. New resources: * `secrets.Kubelet` contains Kubelet PKI derived directly from the machine configuration * `k8s.KubeletConfig` contains Kubelet non-secret config derived directly from the machine configuration * `k8s.NodeIPConfig` contains configuration on picking up Node IP for the kubelet (from machine configuration) * `k8s.NodeIP` contains actual Node IPs picked from the node addresses based on `NodeIPConfig` * `k8s.KubeletSpec` contains final `kubelet` container configuration, including merged arguments, KubeletConfig, etc. It is derived from `KubeletConfig`, `Nodename` and `NodeIP`. Final controller `KubeletServiceController` writes down configuration and PKI to disk, and manages restart/start of the `kubelet` service which is a pure wrapper around container lifecycle.
