Add async finalizers to the request-context about pytest-asyncio HOT 3 CLOSED

Unlike what I thought, it appears that the event loop isn't running inside finalizers. That means that my task would indeed never have been executed.

Consequently, this achieves what I was looking for:

@pytest.fixture
def foo_fixture(request, event_loop):
    def fin():
        async def afin():
            await some_stuff()
        event_loop.run_until_complete(afin())    
    request.addfinalizer(fin)
    return 42

I let you choose to close this issue or not. My point of view is that it would at least deserve a proper documentation. Better API would be nice to have, but since it's py35 only use-case, I don't really see the point, finally.

I can submit a documentation PR for this if you will. Let me know.

My 2c: just document it.

IMO 3.6 asyncio is way better than 3.5 and we (as a community) should steer new developers to 3.6.

@dimaqq Thanks! Can't agree more. The point is that LTS versions of some well-known Linux distros won't get support for py36 unless using third-party packages. So I'll just stick to 3.5 until next LTS.
