BackpressureStrategy<Q, R> class abstract

Class to implement to support a backpressure strategy. This is used to make sure job queues are handled properly.

Examples of implementations of this class are: NoBackPressureStrategy that uses a FIFO stack for handling backpressure. ReplaceBackpressureStrategy that has a job queue with size one, and discards the queue upon adding a new job. DiscardNewBackPressureStrategy that has a job queue with size one, and as long as the queue is populated a new job will not be added. CombineBackPressureStrategy that has a job queue with size one, and uses a combine function to combine input data on back pressure.
