LGTM.
The only thing I'd like to add somewhere(maybe in the doc): for whoever doing BW pe_wave, please apply the normalization with your own yaml config.

* Add Utilization to metric name for Bandwidth related metrics whose Unit
  is Percent

* Update Unit of Bandwidth metrics to Gbps
    * Update metric Formula to use total duration as denominator instead of normalization unit.
    * Update metric Description
    * Update metric Unit

* Update CHANGELOG
