If the fact that we use the same Callable for scanner open and scanner close
becomes confusing. Later might make sense making ScannerCallable abstract
making a CloseScannerCallable and OpenScannerCallable as appropriate.
> Improve exceptions that come out on client-side

> Client-side exceptions should contain regionserver and region client was
> going against. Looking at an UnknownScannerException that came out of a

> cluster has a 20-plus machines and I don't know which I should be looking at.
