Description

This is a sub-task for refactoring the interface of InputGate which would be created by ShuffleService future. So it is reasonable to reference with general InputGate anywhere instead of specific `SingleInputGate`.

To make InputGate extend AutoCloseable interface, the TaskCanceler could call InputGate#close instead of SingleInputGate#releaseAllResources.

Next we can further remove the reference with SingleInputGate in Task class by refactoring the updatePartitionInfo into NetworkEnvironment.
