So should we do this way or after the first RPC in the first region switches to 
STREAM we should use the same mode in all other regions?

I think we can add a field in the ScanResponse to tell the client the suggested 
ReadType for next scan request.

> Return immediately for a scan rpc call when we want to switch from pread to 
> stream
