Is it possible to run alongside gitlab runners?

### Describe your use-case which is not covered by existing documentation.

Our org is currently using both gitlab runners and Jenkins for different parts of our CD pipelines.

I'm wondering if it's possible to run them in parallel and have them both be respected.

In particular, when we have both Jenkins and gitlab runners with merge request pipelines, the Jenkins pipeline will override the failed statuses of gitlab ci jobs. Additionally any artifacts uploaded by the gitlab runners are detached from the merge request, so we aren't seeing a features like [code coverage visualization](https://docs.gitlab.com/ee/ci/testing/test_coverage_visualization.html)

### Reference any relevant documentation, other materials or issues/pull requests that can be used for inspiration.
