`manage.py check --deploy` is now run during Travis testing and as part
of stage/prod/Heroku deployment. It checks for a number of common
configuration mistakes & ensures security best practices are being
followed:

pytest-django doesn't setup a test database for every single test, but
only for those tests that actually require a db. Tests that require a db
need to either be marked with `@pytest.mark.django_db` or use a fixture
that has a dependency on `db` or `transactional_db`.
Using a non transactional db would make tests execution much faster, but
unfortunately it doesn't play well with the treeherder datasource
creation so I used a transactional_db.
pytest-django also allows you to specify a settings file to use for
tests in a pytest.ini file, which is nicer than monkeypatch the original
settings file in the pytest session start function 😃.

flake8 is run on Travis, so let's make it harder to forget to run
locally for people who use runtests.sh. Eventually we should move all of
this to setup.py.
