> For long lived containers we don't want the AM to be a SPOF.
> When the RM restarts a (failed) AM, it should be given the list of containers it had already been allocated. the AM should then be able to contact the NMs to get details on them. NMs would also need to do any binding of the containers needed to handle a moved/restarted AM.
