Add SessionID to SessionStateListener methods

[esanchezros]

Apologies if this has been requested already but I think it will be great if the methods on SessionStateListener interface would accept the Session or the SessionID to identify which session has produced the event. At the moment, I have to pass the session to the state listener when adding the state listener to the session:

((SessionConnector) clientInitiator).getManagedSessions()
		.forEach(session -> session.addStateListener(new MonitoringSessionStateListener(session)));

...

public class MonitoringSessionStateListener implements SessionStateListener {

	private final Session session;

	MonitoringSessionStateListener(Session session) {
		this.session = session;
	}

Thanks

Sounds like a sensible enhancement to me. SessionID should be OK in my opinion.

OK, that's great. I will try to create a PR for this change. Thanks Chris
