      Description

      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.
