Comment 6 for bug 1482758

OK, the problem is that neutronclient doesn't get updated on the new kilo side of grenade past 2.3.12 because it satisfies the requirement:

https://github.com/openstack/requirements/blob/stable/kilo/global-requirements.txt#L132

python-neutronclient>=2.3.11,<2.5.0

But since neutronclient 2.3.12 caps things for juno, we can't use it on kilo due to the conflict and then kaboom.
