rr.serve should be rr.serve_websocket, rr.connect should be rr.connect_tcp

And similarly, rerun --serve should be rerun --serve-websocket (or something along these lines, you get the idea).

Users get understandably confused by this. They expect a serving process (rr.serve()) to be ready to accept connections from other processes (rr.connect()), except the two things are in reality completely unrelated: one is hosting a websocket server to be polled by the web-viewer, while the other is trying to connect to the TCP sdk comms pipeline.

Yet another thing that would make documenting the app model (#919) easier.

Let's just rename these and keep the old names as deprecated redirects
