WebSocket protocol negotiation.
Introduces an Action Cable protocol version that moves independently of and, hopefully, more slowly than Action Cable itself. Client sockets negotiate a protocol with the Cable server using WebSockets' native subprotocol support:
- https://tools.ietf.org/html/rfc6455#section-1.9
- https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Subprotocols
If they can't negotiate a compatible protocol (usually due to upgrading the Cable server with a browser still running old JavaScript) then the client knows to disconnect, cease retrying, and tell the app that it hit a protocol mismatch.
This allows us to evolve the Action Cable message format, handshaking, pings, acknowledgements, and more without breaking older clients' expectations of server behavior.
