> 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*.
