James E. Blair f74ce34d36 Revert "Added parallelization options"
This reverts commit 7100a7f225e60936f23d24c757c1b14c9b136ec4.

The referenced commit, in addition to what it advertises, also
filters the result of update_jobs to include only changed jobs.
If there are no change jobs, then, if the user specifies
--delete-old, there are no jobs in the list of jobs to keep
which comes from the result of update_jobs.  In that case, all
jobs are deleted.  Or in other words, the logic in this change
is that all jobs not updated are deleted.

Proposing as a revert because this is currently causing serious
problems for continuously deployed JJB instances, and the very
common --delete-old code path should be properly tested with
this change before it lands again.
