Tests for UnsentMessageQueuer
The popper worker
Finishing the bean wiring
+ Integration test
Fix the test for changes to MessageReceiver
+ Missed compilation error
+ CloudWatch metric for Popper worker
Experimentation
- Based on changing some constants around, the Queuer should run every 5 minutes
-   The popper should run every 30 seconds
- Queuer should only fill a non-empty queue
