Now that openstack-infra has new roles to build/upload/promote
artifacts from gating, we are making use of them as much as we can.
Mini-mirror was also changed:
- It was wrongly affiliated to SUSE, so that Copyright line was removed.
- The docker file was incorrectly named, and was therefore renamed for
consistency.
The LOCI jobs were not updated, and will be part of another commit.
