commit bc921baf1f96adf1ccb5aec7a8f8a5b6ae66b3bd
Author: Mike Miller <mmil...@apache.org>

    Make CleanUp shutdownNow close Connector (#2332)
    
    * Recent changes in #2303 made static ThriftTransportPool a part of
    ClientContext. In order to allow legacy Connector clean up the threads
    as it did previously, make the shutdownNow method take a connector and
    call close on it. Made null an option in case the Connector is
    unavailable to pass as a parameter.
    * Fixes failure in CleanUpIT. Partial fix of #2327
