Fix Sonar and JaCoCo relationship

* Explicitly enable Jacoco XML report
Must be `xml.required = true`
* Starting with version 3 the Sonarqube Gradle plugin
does not do any automatic dependencies on other tasks:
https://docs.sonarqube.org/latest/analyzing-source-code/scanners/sonarscanner-for-gradle/
* It is also does not apply the task to sub-projects.
So, to make the root `sonarqube` task we need to have config like this:
```
 rootProject.tasks['sonarqube'].dependsOn jacocoTestReport
```
Note: the `sonarqube` task is deprecated in favor of `sonar`,
but that is exactly what our current Bamboo Sonar plugin does.
So, when that is upgraded, we need to revise our config again
* We don't need `xml.outputLocation` since its default is what Sonar expects
