Refactoring of queue/queue-policy:

- moved some logic out of Queue.cpp into QueuePolicy.cpp
- moved QueuedMessage definition into its own header file
- added checks for requeue and dequeue
- split QueuePolicy logic into different sub classes
Added ability to request old messages to be discareded to make room for new ones when configured limit has been reached.
