Comment 4 for bug 1603499

Is this just for barbican-worker or are there others entry points that should have this functionality as well? Looking through I see main routines in:

db_manage.py
keystone_listener.py
pkcs11_kek_rewrap.py
retry_scheduler.py
worker.py

Do you want this in all of those? Any others?

I have some sample code working that works for --version and --help (using parse_args). I'm browsing through the CONFIG processing code to see how it should be included.
