RemoteShuffleEnvironmentshould not registerInputChannelMetricsrepeatedly, which only create once inRemoteShuffleEnvironment#createInputGates.Why are the changes needed?
If a task has multiple input gates, It will create as many
InputChannelMetricsas the number of gates, so the corresponding metrics are registered repeatedly. Therefore,RemoteShuffleEnvironmentshould not registerInputChannelMetricsrepeatedly forcreateInputGates.Backport apache/flink#21437.
