> The status information available from RM is weaker than that available from AM.
> Perhaps rich status from AM can be bundled into a protobuf packet (or JSON) and pushed to RM during shutdown.
> eg during shutdown, set appMessage={AppMaster status + <diagnostic messages>} in parsable format.
> Then the client-side code can be:  get StatusInfoPacket from either AM or RM.  decode packet and populate client-side structures.
