Let's add a note about this to the docs, and should onDisconnect also get the connectionContext as the second arg?

Right now it's weird how onConnect and onDisconnect converge in the information passed to them:

onConnect(params, socket, context)
onDisconnect(socket) // 😢
// Let's make that
onDisconnect(socket, context)
