[Feature] Add WebSocket Token/Basic Authentication

[astubenbord]

Hi, currently, the only way to authenticate a WebSocket connection is to send the sessionid cookie to the server.

As far as I've seen token or basic authentication is not possible.

I'm currently writing an app and I'm trying to visualize the consumer status on document upload to allow the user to directly edit the previously uploaded document once consumption has finished. I would like to do this without using "ugly" long-polling to the
endpoint /api/documents/?query={{filename}} until the document has been consumed and the result is not empty.

Do you think this is something that could be implemented without sacrificing security?

Thanks!
