Comment 9 for bug 1655922

Looks like the isssue is that version of keystone that we have on jenkins slaves on community CI is incompatible with current fuel-qa. Please compare `pip freeze` output in /home/jenkins/venv-nailgun-tests-2.9 virtualenv on ci-slave01.fuel-infra.org (community-ci where we have problems) and on srv114-bud.infra.mirantis.net (product-ci where everything is ok).
