AMBARI-11064 Widgets: Graph change API calls to use null padding rather than
zero padding (graphs are misleading for recent data points as they are shown as
zero when there's no data). (atkach) (atkach:

> Ambari Metrics API have recently changed to automatically pad missing data
> with zeros.
> However, this creates strange user experience where more recent data, if the
> metrics collection is somehow lagging, to drop off to zero. This is
> misleading.
> We should convert the API calls to use null padding and make sure to not show
> any data in case of null (rather than zero).
