Heapter doesn't collect stats from master node

[dchen1107]

Today heapster is enabled by default for both GKE and GCE for monitoring, but it doesn't collect stats from master node. The reason is master node is never register itself to apiserver. I remembered either me or @vishh filed the issue before. But back then, the decision is we are going to use collectd + GCM as the default solution for both GKE and GCE. But decision was changed later, then I filed #9028.

Now I realized that we missed monitoring on master node for both GKE and GCE. cc/ @brendandburns @alex-mohr @roberthbailey @thockin @vishh @saad-ali

@a-robinson has the most GKE context on monitoring.

We may just have to let GCE and GKE differ here, since heapster won't be able to reach the master's kubelet on GKE. It makes sense to re-add this for GCE, though.
