Changes for performing GC. Changes to pass in hdfsServer and port via CQD and remove hardcoding. Changes to pass in lobLocation via CQD and remove hardcoding. Changes to remove all mxlobsrvr process functionality from ExLOBprocess.cpp. Retaining only the infrasturcture so mxlobsrvr process can be used in the future. The executable is still built but the process is not started as part of Trafodion anymore. We may use it in the future.
