Issue eclipse-ee4j#23507 Added jacoco and jacoco-merge profiles

- first is used to extend surefire/failsafe plugins and collect information
  about the test coverage. Results can be imported to Eclipse.
- second is used to collect results from all subdirectories and merge them
  to one file. This can be used to view which code is not invoked by any test
  in the build.
