Towards a1 1.0.0: rmr improvements

    * Upgrade rmr to 1.9.0
    * Upgrade rmr-python to 0.13.2
    * Use the new helpers module in rmr-python for the rec all functionality
    * Switch rmr mode to a multithreaded mode that continuously reads from rmr and populates an internal queue of messages with a deterministic queue size (2048) which is better behavior for A1
    * Fix a memory leak (python obj is garbage collected but not the underlying C memory allocation)
