mod_signal feature suggest: notification of connect/disconnect

[Behrad Zari]

This would be nice to be able to integrate any pub/sub system into mod_signal. In my case, there is a scenario in which I need to get notified when a client connects to a signal, so that I can subscribe to a broker, and emit signals for published messages. I thought that would be nice mod_signal creates a notification (z_notify) with the connect parameters.
