Description

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
