In reviews we usually check import grouping but it is boring. By using flake8-import-order plugin, we can avoid this. It enforces loose checking so it sounds good to use it. This flake8 plugin is already used in tempest. Note that flake8-import-order version is pinned to avoid unexpected breakage of pep8 job. Setup for unit tests of hacking rules is tweaked to disable flake8-import-order checks. This extension assumes an actual file exists and causes hacking rule unit tests.
