> VisibilityController returns false instead of the newValue for the 
> preBalanceSwitch() call.
> VisibilityController extends both RegionObserver and MasterObserver, 
> unfortunately only 1 of the two can use the Base implementation. in this case 
> the BaseRegionObserver is used and all most of the MasterObserver methods are 
> a noop. Any idea on how to avoid reimplementing all the  interface methods as 
> noop, and avoid problems like the preBalanceSwitch()?
