 Title: #5874: [Backport][ipa-4-8] Constrain pylint to supported versions
Action: opened

PR body:
"""
Two, three times a year PR-CI starts failing because tox tests pull in a
newer version of pylint with new warnings. To reduce breakage this
change constraints pylint (and indirectly astroid) to latest tested
minor version. The constraint should be updated when FreeIPA starts to
support a new Fedora version with more recent pylint.
