> The current {{NetworkEnvironment}} would be the default {{ShuffleService}} implementation in task manager. In order to make the interface simple, we try to avoid more interactive with {{NetworkEnvironment}}.
> {{NetworkEnvironment#unregisterTask}} is used for closing partition/gate and releasing partition from {{ResultPartitionManager}}. partition/gate close could be done in task which already maintains the arrays of them. Further we could release partition from {{ResultPartitionManager}} inside {{ResultPartition}} via introducing {{ResultPartition#close(Throwable)}}. To do so, the {{NetworkEnvironment#unregisterTask}} could be totally replaced to remove.
