puppet-openstacklib already has stable branches:

I was not aware of any assumption that openstacklib would work for
different versions of our modules. I think this would be a difficult goal
to achieve. For example, the provider code in puppet-keystone is tightly
coupled with the code in puppet-openstacklib. If making puppet-openstacklib
version-agnostic is important (and I do think there would be value in it)
then maybe we should consider ripping out the provider backend code from
puppet-openstacklib and creating a puppet-openstackclient module.
