manage.py replacement PyTestRunner from docs is broken

The docs (https://github.com/pytest-dev/pytest-django/blob/master/docs/faq.rst#how-can-i-use-managepy-test-with-pytest-django) include a description for how to hook up manage.py to use pytest.

The provided code doesn't work with Django 1.9 for a couple of reasons --

First, run_test has the following signature:

def run_tests(self, test_labels, extra_tests, **kwargs):

(https://github.com/django/django/blob/master/tests/test_runner/runner.py#L19)

And secondly, this command is valid: ./manage.py app1.package.module:TestClass.test_method

But the PyTesetRunner doesn't have any way to unpack module path from the class part.

Thoughts on how best to proceed?

Start with docs/faq.rst and the documented PyTestRunner example, then compare it with Django 1.9's test-runner signature and the module-path command described in the issue. Done means the manage.py integration documented there works with Django 1.9, including the cited module, class, and method form.
