* Adjust all __future__ imports:
for i in $(grep -REl "__future__.*absolute_import" plugins/ tests/); do
sed -e 's/from __future__ import .*/from __future__ import annotations/g' -i $i;
done
* Remove all UTF-8 encoding specifications for Python source files:
for i in $(grep -REl '[-][*]- coding: utf-8 -[*]-' plugins/ tests/); do
sed -e '/^# -\*- coding: utf-8 -\*-/d' -i $i;
done
* Reformat.
* Make all doc fragments, module utils, and plugin utils private.
* Remove some unused and no longer needed imports.
This hopefully also fixes the CI issues, which do not happen locally for me...
* Fix formatting.
* Try to make CI happy, again.
* Fix imports.
* Lint.
