HCC Walltime Effeciency

Rob's post on walltime efficiency was interesting.  I did the same with HCC and found that we had much better efficiency than I expected.  Especially with GlideinWMS's default behavior of sticking around for 20 minutes waiting for a job before exiting.

What's interesting is that we rarely run jobs at RENCI-Engagement, OSCER, or GPGRID.  It's difficult to interpret this.  Since we run so many workflows, it's not clear to me that this means much.
