Support passing custom kwargs to DiscoverRunner's test runner

Currently, there doesn't seem to be a nice way to have Django pass custom kwargs to the underlying unittest test runner when running tests.

This is because Django hard-codes the kwargs it passes (see here for a direct link to the code):

def run_suite(self, suite, **kwargs):
    resultclass = self.get_resultclass()
    return self.test_runner(

Django's default test runner is unittest.TextTestRunner, and here are all of the kwargs that the runner currently supports (from the function signature in Python 3.5.2):

class TextTestRunner(object):

    def __init__(self, stream=None, descriptions=True, verbosity=1,
                 failfast=False, buffer=False, resultclass=None, warnings=None,
                 *, tb_locals=False):

One approach to this ticket might involve having run_suite() pass its kwargs along to the test runner function (instead of "swallowing" them), and making whatever other code changes are needed to support this (e.g. modifying run_tests() to pass kwargs along to run_suite()). More focused approaches are also possible.

Also, to ground this in reality, the use case I am / was interested in is passing a custom stream to the underlying TextTestRunner.
