Description

• Introduces a new `Input` interface to represent the logical input of operators.
• Introduces a new `NetworkInput` class to represent the network input of operators.
• Introduces a new `StreamTwoInputSelectableProcessor` class to implement selectively reading.
• Introduces a new `TwoInputSelectableStreamTask` class to execute the operators with the selectively reading.
• Adds benchmarks for `StreamTwoInputProcessor` and `StreamTwoInputSelectableProcessor` to ensure that StreamTwoInputSelectableProcessor's throughput is the same or the regression is acceptable in the case of constant `InputSelection.ALL`.
