[aiohttp] - add raw setup (no-proxy)

[Reskov]

I decided to revert nginx as the default aiohttp proxy until we figure out what is the root cause of the performance degradation.

I added server.py which creates a socket and spawns multiprocessing with port reuse. Performance is comparable to the gunicorn setup. So I set it as the default.

Might be worth waiting for some results first, just to verify we see the same difference in performance in the benchmarks.

[Reskov]

Yeah, good point! Let's wait a week until benchmark will start and finish. I convert to draft.
