 - requestNewAuthToken will clear the token if it fails.
 - request auth token on every retry, not just after 403
 - update to use nopoll v 1.0.2
+- Add pause/resume heartBeatTimer
+- parodus event handler to listen to interface_down and interface_up event
+- Pause connection retry during interface_down event
