> In current "pluggable shuffle service", IndexedInputGate defines the reading 
> for a single intermediate result (doc of InputGate) and InputChannel defines 
> a single reading channel in IndexedInputGate. IndexedInputGate consists of a 
> number of InputChanels. Current fields of InputChannel are mainly some 
> descriptions or metrics for a single channel. But we found SingleInputGate is 
> mixed in. From our understanding, SingleInputGate is a specific 
> implementation in "Netty shuffle service" and should not be exposed by 
> "pluggable shuffle service".
