Code review comment for lp:~jaypipes/glance/use-paste-deploy

Great cleanups Jay, thanks!

I'm marking Approved b/c what follows are nits that shouldn't necessarily hold up patch. I'll leave to your discretion whether they should be fixed with this merge:

* options_to_conf is no longer used, so we can strike that as well
* the defaults regex code is no longer used (outside of tests) so we can strike that as well

I think with both of those removed, common.config will be pretty clean.
