pylint

• pylint should be installed already as part of requirements-dev.txt
• pylint behavior can change dramatically between even micro releases of pylint and astroid (the underlying package used by pylint to parse Python syntax), so it's important that the supported version is the same (requirements-dev.txt specifies the right versions)
