> Observed that chaos monkey was killing the wrong RS when performing chaos actions like RestartRSHolingMeta, RestartRandomRSExceptMeta etc. This is because we use the cached region location that turns out to be false in subsequent actions.
> More specifically in DistributedHBaseCluster.getServerHoldingRegion(..)
> we use regionLoc = locator.getRegionLocation(regionName) which does not reload the cache.
