Partial CI Config

Taken from https://docs.gitlab.com/ee/user/project/merge_requests/test_coverage_visualization.html#gradle-example and slightly modified:

• needs Job name changed
• cobertura report exchanged with the newer coverage_report
• rules changed to fit the workflow

coverage-gradle:
  stage: test
  needs:
    - test-gradle
  image: registry.gitlab.com/haynes/jacoco2cobertura:1.0.7
  script:
    - python /opt/cover2cover.py build/jacoco/jacoco.xml $CI_PROJECT_DIR/src/main/java/ > build/cobertura.xml
  artifacts:
    when: always
    reports:
      coverage_report:
        coverage_format: cobertura
        path: build/cobertura.xml
  rules:
    - if: $NAB_DISABLE_COVERAGE
      when: never
