Background

The block buffer service should use a configurable set number of blocks for the buffer instead of being based on wall clock time and configurable TTL.

In addition, take a look at perhaps blocking the transaction handling thread in HandleWorkflow. Specifically perhaps we should block/wait there vs creating a completable future on another thread (pruning thread) as that could lead to more than the set number of blocks being opened in the buffer. (Since the pruning thread runs on wall clock time).
