Updated openstack/openstack
Project: openstack/django_openstack_auth  04d376f6cb05fcba2e6c8039e402f6916dd7ac31

Minor update to the readme file

The directory name seems to have changed from "keystone_auth" to
"openstack_auth", but the readme still points to the old directory name.
This patch fixes it.
