Add RHEL 9.0, Ubuntu 22.04 and Fedora 36 to CI (#358)

* Add RHEL 9.0 to CI.

* Add RHEL 9 specific files.

* Add Ubuntu 22.04 and Fedora 36 to CI.

* Another try.

* Adjust kernel memory tests.

* Add more details.

* RHEL 9 doesn't support setting memory swappiness.

* Fix docker_swarm_service tests.

The 'less' case should always have been changed, but it probably was always skipped
due to a too old Docker SDK for Python or a too old Docker daemon.

* More checks / improve checks.
