Comment 13 for bug 1473525

So it seems this issue make more sense to fix once https://github.com/ansible/ansible-modules-core/pull/2696 has been merged.
That fix will add the option to specify a fixed filename for a repo configuration.
Other then that we can only proceed with https://review.openstack.org/#/c/201696/ which would remove old files before putting a new config in place.
