I think (iirc) that markmc and I were talking about both an ultimate
ending point and a way to get there.

As in - start with the code in openstack-common for right now, get
things working, get everything happy.

THEN - because this is actually missing the python world in general, we
can perhaps pull out the functionality into a library that we land
either on pypi or even (if I have my way) in python core. Then
openstack.common could just consume that.

But a decision on the eventual home of a sensible library which handles
both config files and command line options shouldn't really block us
from moving forward on intra-project collaboration at the moment.
