Milestone #6025: Release JobSub v0.3
jobsub_client ups/upd packaging does not work with SL6
jobsub_client sets up pycurl. This is required on SL5 as system pycurl is not new enough. However this does not work with SL6 where jobsub client should be using the system pycurl. In the jobsub_client's table file we need to set pycurl conditionally if the system OS is SL5 variant.
