pytest-aiohttp: compatibility with pytest v3.3.0

[popravich]

Long story short

pytest-dev/pytest#2959
Fixture parameters are now immutable, pytest_plugin.py need to be updated

[asvetlov]

Fixed by #2573

Would it make sense to put code into pytest-aiohttp package? In cases like this, a new release of aiohttp is needed and not all the users are prepared to upgrade their aiohttp version just to use the latest pytest.

So for now, either users have to live with this until they upgrade or this could be backported to previous versions. IMO having this separated in pytest-aiohttp would make life easier

[asvetlov]

pytest-aiohttp is tightly coupled with aiohttp itself.
Keeping everything in the single code base simplifies testing aiohttp itself and checking that everything is working without problems.
Introduced pitfall requires a new pytest-aiohttp release though just to note people that problem is fixed.

Anyway pytest-aiohttp provides guarantee for the latest aiohttp only (the same policy as for aiohttp-session and other libs. Supporting a matrix of compatible versions is nightmare.
