Change the release of Ceph from 12.2.3 (Luminous) to latest 13.2.2
(Mimic). Additionally use supported RHEL/Centos Images rather then
Ubuntu images, which are now considered deprecated by Redhat.
- Uplift all Ceph images to the latest 13.2.2 ceph-container images.
- RadosGW by default will now use the Beast backend.
- RadosGW has relaxed settings enabled for S3 naming conventions.
- Increased RadosGW resource limits due to backend change.
- All Luminous specific tests now test for both Luminous/Mimic.
- Gate scripts will remove all none required ceph packages. This is
required to not conflict with the pid/gid that the Redhat container
uses.
