 * [optional] **API driven CA** Optionally, we will run a CA in the master that will mint certificates for the nodes/kubelets.  There will be pluggable policies that will automatically approve certificate requests here as appropriate.
   * **CA approval policy**  This is a pluggable policy object that can automatically approve CA signing requests.  Stock policies will include `always-reject`, `queue` and `insecure-always-approve`.  With `queue` there would be an API for evaluating and accepting/rejecting requests.  Cloud providers could implement a policy here that verifies other out of band information and automatically approves/rejects based on other external factors.
 * **Scoped Kubelet Accounts** These accounts are per-minion and (optionally) give a minion permission to register itself.

 To facilitate recovery in the case of a crash of the updating process itself, we add the following annotations to each replicaController in the ```kubernetes.io/``` annotation namespace:
