This change cleans up the pod manager extensively so that * Mirror pods are actually stored in the pod manager. * Both (non-mirror) pods and mirror pods are indexed by UID and full name for easy lookup and mapping. This is required for the next change to send full pod along with the pod status update. This change also renames mirrorManager as mirrorClient since it is merely a client to contact the API server and create/delete mirror pods.
