> Implement a scan works like the grpc streaming call that all returned results
> will be passed to a ScanObserver. The methods of the observer will be called
> directly in the rpc framework threads so it is not allowed to do time
> consuming work in the methods. So in general only experts or the
> implementation of other methods in AsyncTable can call this method directly,
> that's why I call it 'basic scan'.
