Bump pylint version to support python 3.8
As spotted in Focal testing patch [0], pep8 test fails with many
C0321 false-positives, reported in pylint as current version does not
support python 3.8 [1]

Use a newer version of pylint and astroid, fixing or disabling some of
the new checks: no-else-*, unnecessary-comprehension, import-outside-toplevel
