Bump pytest-asyncio from 0.15.1 to 0.18.2

[Kludex]

Replaces #1408

This PR adds the asyncio_mode=auto option as well. Which means that @pytest.mark.asyncio markers can be removed.

Previous approach raised errors, which I don't have the time to solve. In any case, this PR just bumps pytest-asyncio, and adds the configuration that is needed to match the behavior we had on 0.15.1.

Both approaches fail with the same error. 😞

I'm game looking at this

ok I spent 2h and I'm nowhere close to understand what the f** happens on windows, those warnings about unclosed resources are insanely hard to debug

[euri10]

the thing I really dont get is why it fails with anyio ??
E KeyError: 'anyio._backends._asyncio'

[euri10]

I think the root issue may be that on windows the closing of the ssl context is too slow but I'm not yet entirely sure

[agronholm]

I recall there was a bug regarding unclosed sockets in asyncio that was fixed in later versions of CPython. I do wonder why you're only hitting it now though.

and only on windows, and it differs between 3.8 and 3.9
will try to find that report @agronholm but if you find it before dont hesitate :)

Hmmm... The 3.8 versions are different between those two OS: windows is using 3.8.10, ubuntu is using 3.8.12.

[agronholm]

I've just ignored those in the AnyIO test suite: https://github.com/agronholm/anyio/blob/master/pyproject.toml#L41

There's no 3.8.12 for Windows yet...

probably the smart move, I'd like though to do that only on windows since we have zero issues on macos and linux

[Kludex]

Let's drop pytest-asyncio and use only anyio, as we already have this dependency via httpx.
