Expose connect and disconnect events to signal routes #1547
Description
Describe the Change
Expose connect and disconnect events to signal routes.
For connect, it would also be nice to manipulate ClientId similar to SSE.
For disconnect, it was mentioned the server doesn't recognize client disconnects, rather it finds this out when attempting to send a message, fails, and then cleans up the connection. This cleanup step is what I'm after as it would be nice to run additional commands at this point.
