This warning was globally disabled in commit c124ab2, due to dynamic
attributes of the `LoopInfo` class. This false positive is silenced
locally now. Some actual positives have meanwhile made it into the
code base, but have fixed via previous commits so we can now enable
W0201/attribute-defined-outside-init again.
For now disable some new warnings from pylint:
- `consider-using-from-import`
- `consider-using-with`
It probably makes sense to re-enable these in the future but
for now lets keep the code as is.
Create a setup.cfg file and move the pylint settings from .pylintrc
here. This file can be used to configure other tooling as well, so
it is in general more useful as a central configuration place.
