Comment 17 for bug 1425552

The main problem is in old version of oslo.utils: https://github.com/openstack/requirements/commit/efb080e744f7466942f977ae79ec2d74501494f6

our version is 1.2.1, but it should be >= 1.4.0. And when service swift-proxy start, it check requirements.txt file.

Keystoneclient requires oslo.utils==1.4.0. That's why this problem happens. So, it should be another bug.
