Indicate adherence to coding standard

[Sancretor]

Is your feature request related to a problem? Please describe.

The report indicates which Quality Profiles we are using, and which anomalies are detected, but it does not indicate the compliance to the coding standard : how much of the Quality Profiles rules are not violated.

Describe the solution you'd like

In a Synthesis/Metrics table, add a new column to indicate the adherence to coding standard in % (ie. % of rules in all Quality Profiles we are not violating).
Round the result to the first decimal place.
