------------------------------

             Summary: Refactor metric chart render process to improve user experience.
                 Key: EAGLE-868
                 URL: https://issues.apache.org/jira/browse/EAGLE-868
             Project: Eagle
          Issue Type: Sub-task
            Reporter: Hao Chen
            Assignee: Chang chen
            Priority: Minor


*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.
