core (xmpp): advanced handling of connection termination factory's clientConnectionFailed and clientConnectionLost methods are monkey patched to allow client to tune termination: - a warning when connection is lost in an unclean way - connector is saved to allow to disable automatic reconnection and retry manually later - new triggers connection_failed and connection_lost allow plugins to tune connection termination workflow
