Running `ServerKillingChaosMonkey` via `RESTApiClusterManager` for any duration of time slowly leaks region servers. I see failures on the RESTApi side go unreported on the ChaosMonkey side. It seems like `RuntimeException`s are being thrown and lost. `PolicyBasedChaosMonkey` uses a primitive means of thread management anyway. Update to use a thread pool, thread groups, and an uncaughtExceptionHandler. Signed-off-by: Bharath Vissapragada <bharathv@apache.org> Signed-off-by: Viraj Jasani <vjasani@apache.org>
