Review comment:
I have some basic thoughts for the concerns of `ResultPartitionID` AND
`subpartitionIndex`.
The baseline is that we can not break the existing rules that
`ResultPartitionID` is different for every input channel but
`subpartitionIndex` is same for all.
- `ResultPartitionID`: We can pass a desired value directly while
constructing the `InputChannel` instance instead of getting it from
`NettyShuffleDescriptor` now. Although it is still not consistent between
`NettyShuffleDescriptor` and `InputChannel`, it becomes consistent in all the
places inside channel, and we also avoid hacking the override method of
`getPartitionId` in `TestRemoteInputChannel` below.
- `subpartitionIndex`: We can keep it same as now. Although we can also
maintain this info in the `InputChannel` layer as did above, then we can also
pass the desired subpartition index while constructing the `InputChannel` to
further void hack `requestSubpartition` method. But considering it is same for
all the channels in normal case, so it might be more reasonable to maintain it
in gate layer as now.
