> _XceiverServerRatis#calculatePipelineBytesWritten_ is called every time we
> send a pipeline report, This method goes through all the containers to filter
> out those container belonging to a pipelineID. In a dense DN, this would
> cause a bottleneck when we send pipeline report. It would also cause a
> rippling effect as the pipeline creation will become slow and the pipeline
> scrubber in SCM will close this pipeline if the DN doesn't create the
> pipeline within the time. The DN will consisently be in a loop to create and
> close pipeline which would make the DN unresponsive.
> This _calculatePipelineBytesWritten_ is only used by a metric in SCM and thus
> it should be removed. These aggregations need to be done by Prometheus.
