Comment 7 for bug 1482758

I think this is a requirements bug not necessarily a neutronclient bug.

python-neutronclient has an overlapping range between juno and kilo:

stable/juno: python-neutronclient>=2.3.6,<2.4.0
stable/kilo: python-neutronclient>=2.3.11,<2.5.0

In this case, keystonemiddleware is upgraded to pulls in a newer oslo.serialization, but that offends stable/juno's oslo.serialization>=1.0.0,<=1.2.0 (which python-neutronclient 2.3.12 correctly includes in its requirements.txt)

TBH I dont' really remember the consensus on the overlaps. I thought we added those specifically to ensure grenade upgrades work with the client libraries held back, but looking at the current state of g-r it looks they are not consistent across all of the client libs.
