Since NN already has provided necessary information to calculate histogram of DN usage, it can be done in JS side. was: In addition of *Min/Median/Max*, another meaningful metric for cluster balance is DN usage rate at a certain percentile (e.g. 90 or 95). We should add a config option, and another filed on NN WebUI, to display this.
