Subject: [PATCH 1/2] Set undefined env variables using CLI arguments Both
 `DJANGO_SETTINGS_MODULE` and `DJANGO_CONFIGURATION` are required for
 `django.configurations.importer` to install, else it throws an exception. If
 the `importer` is not installed, `django.setup()` fails on
 `configure_logging(settings.LOGGING_CONFIG, settings.LOGGING)` when trying to
 access uninitialized settings.

fixes #309 (https://github.com/PyCQA/pylint-django/issues/309#issuecomment-817098961)
fixes #325
might relate to #362
