Comment 3 for bug 1653693

@Roman, as I mentioned - 6.0.0 works fine and it uses "project_id" too - https://github.com/openstack/python-novaclient/blob/6.0.0/novaclient/client.py#L836

There is an issue in novaclient somewhere in session initialization. Fast solution is to pin novaclient<7.0 version, good fix - move OSTF to keystone session instead of user-password auth (and pin novaclient>=7.0 after this)
