Drop Python < 3.8 and replace pkg_resources with importlib

This would kill Python 2 compatibility, no?

Version 3.3.1 still had Python 2.7 support: https://pypi.org/project/importlib-resources/3.3.1/

let's find out by fixing CI on 2.7: #38

Thanks! Looks good then.

One oddity I still can offer. https://github.com/theforeman/jenkins-jobs/blob/master/theforeman.org/pipelines/lib/obal.groovy does not pip install anything, but just checks out obsah and obal and mangles PYTHONPATH. That means it'll break with this change unless we somehow ensure importlib things are installed.

(pip install probably won't do as we don't use a venv right now? need to investigate)

given on EL8 we use py3.11 now, this is safe to merge once we turn of the el7 builders.

[ekohl]

Should we then refactor this in a "drop Python < 3.8 compatibility" PR?

[evgeni]

I think downstream it's still py3.6 (with whatever ansible is compatible with that)

[ekohl]

Do we still need to care about this or can we assume Python 3.8+ by now?
