Add a little bit of documentation to NotifyPods

Browse Source 
As far as I can tell, based on the implementation in MockProvider
NotifyPods is called with the mutated pod. This allows us to
take a copy of the Pod object in NotifyPods, and make it so
(eventually) we don't need to do a callback to GetPodStatus.
