Iot dashboard: Make circular progress bar a QskControl (#124)
* IOT example, circular progress bar: Use a pen instead of a brush

That way we don't have to draw two circles, and we can in addition
use a conical gradient.

* IOT example: Make circular progress bar a QskControl

... and internally use a QskPaintedNode for now. By doing this we
already have the API ready (similar to QskProgressBar) and can
swap the QskPaintedNode with an arc renderer at a later point in
time.
