> When user selects any service component like All NameNodes or Datanodes (*and not a specific host component like Active namenode or Active ResourceManager*), Add metric popup should show an additional label *Aggregator Function* at the end and a corresponding bootstrap button/dropdown having following options:
> * avg
> * sum
> * min
> * max
> By default avg should be selected. Selected value from the dropdown should be shown on the button. Hovering this dropdown should show a popover with text "This mathematical function will be applied to compute single value for selected metric across all host components".
> If user selects any option other than avg, metric path should be suffixed with ._$\{aggregator function name\}. For example if user selects a metric with name *regionserver.RegionServer.numOpenConnections*. It's corresponding metric path as known from API data obtained from metrics descriptor is *metrics/hbase/ipc/IPC/numOpenConnections*. If user then selects an aggregator function *sum*, metric path prepared for the metric element in the metric Array of the widget API definition should be saved as *metrics/hbase/ipc/IPC/numOpenConnections._sum*.
