In python3, super() does not always require a class and self reference. In other words, super() is enough for most cases. This is much simpler and it is time to switch it to the newer style. pylint provides a check for this. Let's enable 'super-with-arguments' check. NOTE: _prepare_mappings() method of FormRegion in openstack_dashboard/test/integration_tests/regions/forms.py is refactored. super() (without explicit class and self referece) does not work when a subclass method calls a same method in a parent class multiple times. It looks better to prepare a separate method to provide a common logic. Change-Id: Id9512a14be9f20dbd5ebd63d446570c7b7c825ff
