- post merge
- postman test
- pr validation
- scan
- sonar cloud coverage

Add dockefile multistage and delete the native-micro. This new dockefile provides the way to build also the app jar instead of making only the image build. That makes possibile to build the app and run it in an image locally directly building it through docker.

Change the application.properties to get the values from the pod config map, previously mounted by the helm chart.

Change the postman test to work with the new URL ( CSTAR ) and not anymore by the container app.

To make liveness and readiness probe work:
Run:

mvn quarkus:add-extension -Dextensions='smallrye-health' (to add this dependency)
mvn depcheck:generate (to update the sha)
mvn clean install -U (to check that the repo build correctly)
The endpoint exposed by this dependency to check read and live are:

/q/health/live
/q/health/ready
