dataRef overrides

This extends the panelConfig to support dataRef overrides at the
label, labelColor, fillColor level. This allows people to configure
thresholds from a different data source. i.e. they might have a
normailized metric for thresholds alongside the actual value metric
that should be displayed.

This also completes the tidyup of the troublehooting->debugging rename.
