[PATCH 00/10] A couple of CI improvements

Hi,

this patch series addresses a couple of issues I've found while investigating flaky CI jobs. Besides two more fixes for flaky jobs it also removes some stale code and simplifies the setup on GitHub Actions to always use containerized jobs on Linux.

Test runs can be found for GitLab [1] and GitHub [2].

Thanks!

Patrick
