- remove all references to cgroups v1. That code never worked,
and "cgroups v2" in test names was misleading because it
implied an alternative. Remove it.
- refactor podman remote and local tests
- clean up docs
- Ansible bitrot cleanup ("this is deprecated, use that")
Tested using 1minutetip but even so this is a big change and
we need to be prepared for fallout in the next bodhi.
