> If you have a StreamingDataFrame with an aggregation, we report a metric called stateOperators which consists of a list of data points per aggregation for our query (With Spark 2.1, only one aggregation is supported).
> These data points report:
>  - numUpdatedStateRows
>  - numTotalStateRows
> If a trigger had no data - therefore was not fired - we return 0 data points, however we should actually return a data point with
>  - numTotalStateRows: numTotalStateRows in lastExecution
>  - numUpdatedStateRows: 0
