Open Stack

I just ran into this issue because I was installing a package that was
bringing in keystonemiddleware 1.5.x which was downgrading pbr to <1.0.
I fixed this problem by upgrading keystonemiddleware to 2.x.x with:

pip install -U keystonemiddleware

After that, devstack worked fine again.

This break happened after the RDO packages used in devstack were changed
from Juno to Kilo.
