Comment 9 for bug 1600281

I've added neutron back to this bug report, because we need to sort out which version of neutron-lib is correct for mitaka. 0.0.2 was marked as part of the mitaka release, but its contents do not appear on the stable branch. Should we change the constraints list to only allow 0.0.1, or do we need 0.0.2 and therefore need to back port its contents into the correct branch?
