> Add a chaos action that will turn down region size.
> * Eventually this will cause regions to split a lot.
> * It will need to have a min region size.
> Add a chaos monkey action that will change split policy
> * Change between Uniform and SplittingUpTo and back
> Add chaos monkey action that will request splits of every region.
> * When regions all reach the size a the exact same time the compactions add a lot of
work.
> * This simulates a very well distributed write pattern reaching the region size.
> Add the ability to start with fewer regions than normal to ITBLL
