Description

In SingleInputGate#create, we could remove unused parameter ExecutionAttemptID.

And for the constructor of SingleInputGate, we could remove unused parameter TaskIOMetricGroup.

Then we introduce createSingleInputGate for reusing the process of creating SingleInputGate in related tests.
