scripts: Remove pylint

pylint has been a great tool to get the initial code base into shape
but since then we mostely false postives. All those warnings needed to
be annonated.

This allong wouldn't be reason enough to remove it. The main problem
is that the pylint version on gitlab is updated in the back and
suddenly we get new warnings which are bogus.
