It's currently 1.12.0, according to
http://git.openstack.org/cgit/openstack/requirements/tree/global-requirements.txt#n95

If we need to ensure that a new feature is present, we can raise that
minimum by patching that global-requirements.txt file and then letting
the bot propose the changes to all of the projects.
