> *Problem*
> Currently when initially loading hbase metric page, there will be relatively long time
that the whole metric dashboard is blank, then all charts and data are rendered at same time.
> *Improvements*
> * Refactor the metric load logic to : Load metric chart config -> show metric chart
placeholder (show blank chart with no data) and show "data loading icon" for each chart one
by one -> load metric data query for each chart -> reader metric data into metric chart
when response returned and remove "data loading icon" one by one.
> * Add "loading-in-progress icon" with appropriate description during any long-time actions.
