RHEL8.4 available | Retired 8.0 and 8.1

RHEL8.4 was GAed Tuesday. We have FOG images for it in the lab now. qa yamls should be updated accordingly. As a side note, I'm going to start cleaning up old versions more aggressively. I had incorrectly assumed nothing was using the RHEL 8.0 or 8.1 images anymore so I deleted those repos from the Satellite server. RHEL 8.0, for example, is over 2 years old. The latest distros we have and should be targeting now are: Ubuntu Focal 20.04 CentOS 8.3 RHEL 8.4 CentOS 8 and 9 Stream -- David Galloway Senior Systems Administrator Ceph Engineering
