Consolidate websocket protocol tests

[kristjanvalur]

Move tests for the websocket protocols (graphql_ws, graphql_transport_ws) into a separate place (tests/websocket)
where they can be parametrized and run on the four different integration which support websockets.

Description

Previously, websocket tests were duplicated for the aiohttp, asgi, fastapi and channels integrations, with both
protocols having a full set of tests in each.

Following what has been previously done with http, we now extend the abstract HttpClient classes in tests/http/clients
to provide async websocket functionality, parametrize the unit tests, and write them once.

This makes it easier to maintain a coherent set of unittests for the websocket protocols, while ensuring that they
do get executed for all of the available integrations.

I like this a lot, thanks! :D

I'm going to remove the release file, hope that's ok! I think we can skip the release since we are updating just tests 😊

[patrick91]

@kristjanvalur I can't push, can you remove the release file? 😊

[kristjanvalur]

yes, about the pushes, I'm using an organization repo for this, policy doesn't permit external pushes.
