When defining a quality gate for a given profile, we might want to define a "Quality Gate" project dashboard to monitor it (see
SONAR-4798). In this dashboard, we would like to display differential measures for any kind of metric, including the "new_*" ones like "New violations" - which is not possible yet.
Note that if the "Custom Measure" widget is configured with a "new_*" metric and displayed without a period, the following message should be displayed to warn the user:
The metric configured for this widget can be displayed only in differential mode.
