Remove sonar/jacoco report configuration

Remove sonar/jacoco report configuration

Sonar no longer supports binary jacoco reports, only XML reports.
We should not be setting the property to direct sonar, as it is
the caller's (Jenkins job's or operator's) responsibility to provide
correct pointer.

For old versions it should point to individual reports, for new
aggregates, such as MRI projects it should point to the aggregated
XML report (${project.root}/target/site/jacoco-aggregate/jacoco.xml).
