Addition of data label series for Power KPI 2.0.0 Visual

[A_Gonzo]

While using the Power KPI 2.0.0 visual I noticed that there is no way to customize the data labels by series.  I believe it will be helpful to update this visual to include series customization.

In my case I would have like to remove the data label on a value that remains a constant, see below. The series represented by the blue line is my constant, having the data labels on this series does not provide much value, it is simply a target line for my KPI. It would be good to remove the data label and only keep the data labels for my green line which would declutter the visual.
