let removed jobs to be listed in the condor_q output

[aleita]

By default when you remove a job from condor queue it is also immedetialy removed from the condor_q jobs list. We have seen that in this condition BLAH/CREAM does not update the job status so the job remains in the last registered status for two months [blah default purge interval]. With high jobs cancel rate the DB can grow indefinitely, slowing the queries thus lead the CREAM CE to an unresponsive status.

Here at INFN-Bari T2 HTCondor cluster the JOB_IS_FINISHED_INTERVAL knob is set to the default 0,
because we can access to the job information using the condor_history command.
But from blah/CREAM point of view it is mandatory to have access to the removed job trough the condor_q command. For this reason the "leave_in_queue" knob in the file "src/scripts/condor_submit.sh" should care about the removed jobs too.
