Fix for running LSF DRMAA jobs as 'real' user.
Fix thanks to Chong Chen at IBM - "When invoking the LSF drmma api to submit a job, the API will print the message like 'Job <78> is submitted to default queue <normal>'. So if the Galaxy want to use this API, need modify the drmaa_external_runner.py script to handle this message.  LSF already support a env variable to disable this message print out, "BSUB_QUIET", set this into env can disable this message output."

A second issue was related to subsequent querying of the job state as a user other than the submitter - according to Chong Chen this has been fixed in latest LSF DRMAA changes on github (https://github.com/PlatformLSF/lsf-drmaa/commit/43e62546172b90d9f95e90273d77f4c35a0bb404).
