Keystone has, I think, validated the set of oslo libraries that it
uses: gettext, jsontutils, importutils, crypto, and policy.
gettext and jsontutils I'd be OK with these in the same library, but
split is fine. I think we sync down gettext and jsontutils, more often
than any others.
Should importutils stand alone? Seems reasonable.
Crypto is a pretty strong contender as well. I think it might make
sense to move it to a single file instead of a subdir.
Would it be possible for Keystone core to be considered the maintaners
of oslo.policy? We seem to have the most people focused on RBAC and
policy enforcement, and it seems to be a natural fit. Policy was
origianlly under Keystone.
We should also have an auth library. I could see huge pieces of
python-keystone client ending up in there. Again, this would probably
be best owned by the Keystone team, at least to start.
