Description

At the moment NetworkEnvironment#getNetworkBufferPool is called to add network related MetricGroup. In order to simplify the public API in NetworkEnvironment which is regarded as default ShuffleService implementation, we could pass the TaskManagerMetricGroup into constructor of NetworkEnvironment, then the related network MetricGroup could be added internally.
