Comment 2 for bug 1628094

I believe this should have been fixed by https://github.com/openstack-dev/pbr/commit/6fdf4e1086c53adf47561697cf82417e1f3b14ed#diff-6c5d8c88de993e859c6554c87ef9b096

It allows configuration of the listen address. If the unrecognized argument bug still exists please open a separate bug so we can track it properly. Thanks.
