8df33bc1a7 Register the kubelet on the master node with an apiserver. This option is 
separated from the apiserver running locally on the master node so that it
can be optionally enabled or disabled as needed.

Also, fix the healthchecking configuration for the master components, which
was previously only working by coincidence:

If a kubelet doesn't register with a master, it never bothers to figure out
what its local address is. In which case it ends up constructing a URL like
http://:8080/healthz for the http probe. This happens to work on the master
because all of the pods are using host networking and explicitly binding to
127.0.0.1. Once the kubelet is registered with the master and it determines
the local node address, it tries to healthcheck on an address where the pod
isn't listening and the kubelet periodically restarts each master component
when the liveness probe fails.

94ae0a9a0d Make the kubelet on a GCE master check instance metadata for manifests. 
Primary motivation: enable GKE and other cluster-as-a-service folks to
easily run additional logic on the master without having to modify salt
or SSH to the master after it's been created.

60d822435b Salt: clean daemon_args on RedHat, not systemd 
I don't think it actually makes a difference based on how we're using it,
but this is now more of a precise change.

that Salt doesn't issue a daemon-reload.

2426366ec8 Update cAdvisor with moved docker root on AWS 
We set up a symlink now, and we also pass docker_root into the kubelet.

The symlink is probably sufficient, but doing both feels safer.

6c219885e0 s/apiservers/api_servers/ in Salt 
It looks like api_servers finally won this battle. Kill off the
last remaining places passing it, but allow the kubelet Salt to
accept apiservers for a period of time.
