This introduces flake8 and fixes a bunch of flake8 errors.
flake8 is run with: ./venv/bin/flake8 plinth
if you're using a python3 venv.
We can eventually further integrate this with gitlab ci.

Fixtures cannot be currently included into other fixtures by using
@pytest.mark.fixtures('fixture_name')
They have to be included as parameters instead.
See bug: https://github.com/pytest-dev/pytest/issues/3664
Also increase the scope of needs_root to the highest, i.e. session, so that it
can be used by any kind of fixture.
