support unix sockets

[PythonFZ]

When running on the same machine, check if you can use unix sockets instead of websockets to -> reduce the communication overhead on the websocket server and have much faster communication.

What if I have the server and client a running on the same machine -> unix sockets are available and client b is running on another machine, thus need websockets.

[PythonFZ]

we somehow need to establish how two clients communicate here?

for this, we could - upon initial communication establish how they can connect?

There is sort of an order in performance degredation

1. https://docs.python.org/3/library/multiprocessing.html#multiprocessing.Value combined with locks / semaphores
2. unix sockets
3. redis / websockets

The initial connection should always be via websockets and then we find the fastest connection possible from there.

check how / if redis can do this.
