--------------------------------------------------------
I don't want to make every wait strategy configurable since it will increase
the test matrix. Actually TimeoutBlockingWaitStrategy in RequestProcessorImpl
should not be changed since it will result infinite loop otherwise. I think
only two combination makes sense:
High throughput: Use BusySpinWaitStrategy for
PersistenceProcessorImpl/ReplyProcessorImpl/RetryProcessorImpl
Low cpu: Use BlockingWaitStrategy for
PersistenceProcessorImpl/ReplyProcessorImpl/RetryProcessorImpl
I only open these two options in the patch.

> Currently tso-server use 300% cpu even at idle time. The reason for this 300%
> cpu usage is due to the BusyWaitStrategy used in disruptor. While this is
> good for throughput, it wastes resources in many use cases. In this ticket, I
> provide a config to use a different wait strategy and reduce the cpu usage
> with the option on.
