> 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.
