I think the long-term hope for this code is for it to move behind the
Tuskar API, so at this stage the library is mostly to bootstrap that
development to the point where the API is more or less settled. In that
sense stackforge seems like a natural fit, but if folks feel strongly
that it should be part of TripleO (i.e. in the openstack namespace) from
the beginning then there's probably nothing wrong with that either.
