Switch Y-WebSocket server from Node to Python

[davidbrochart]

Closes #728.

[davidbrochart]

8e8c18f replaces the Node-based Y-WebSocket server with a minimal pycrdt-websocket server.
For now, this Python server has to be run manually with:

python src/backend/servers/y-provider/server.py

This currently needs y-crdt/pycrdt-websocket#130.

With 5709d9b there is no need to manually start the Python server anymore, it's integrated in Docker.

Hi,
I was wondering if it's possible to integrate it with the current django application or not ? Otherwise I don't see advantage to switch from node to python.

[davidbrochart]

Sure, the goal is to get rid of the separate Python server and integrate it with the Django application. It's easy if the Django server is ASGI. I understood that it's currently WSGI but that you are planning to switch to ASGI?
