Remove all version references to obsolete pytest versions

Remove version references to pytest 2 and 3.

Just like Python 3 no longer has references to Python 2, I think
we should follow the same approach in pytest.

 pytest's marker implementation traditionally worked by simply updating the ``__dict__`` attribute of functions to cumulatively add markers. As a result, markers would unintentionally be passed along class hierarchies in surprising ways. Further, the API for retrieving them was inconsistent, as markers from parameterization would be stored differently than markers applied using the ``@pytest.mark`` decorator and markers added via ``node.add_marker``.
