Python 2 packages are no longer available on Fedora 30+, and therefore it's not even possible to run the test suite there. Change devguide to target Python 3 by default.
I was actually thinking about kicking out all the Python 2 bits (eg. rpm deps in devguide), but that can surely be done at a later point.
LGTM otherwise, rebase and feel free to merge.
