Move RHEL branch to TMT

Advantages:
- Test RHEL branches on on actual RHEL
- Reduce our GCE/AWS usage
- Easier to switch git host (RE: CNCF)

Note: This setup does not do rpm builds, binaries are built from source
itself using Makefile. There's no clean and reliable way to fetch actual
RHEL spec files using packit, and CentOS Stream spec files can't be
depended on as they move at a faster pace and can be out of sync with
RHEL release spec files.
