qa: configure linting to fail on >80 columns wrapping

added QA label

Django is switching to Black for code formatting. Maybe we should follow the same convention.

Black does not support any form of xml output. However it does support a diff output ou stdout but as far I know gitlab can't understand this format. It will be difficult to have a seamless integration with gitlab... We can, however stick with pylint as a syntax checker.

But we can still incorporate black into our project. We can either add black as a pre-commit hook (https://github.com/python/black/blob/master/README.md#version-control-integration) or put a script to execute it. Projects that use black use both of these techniques.

Black recommend that we use 88 as a max length for columns. I suggest that we do the same.
