Use CI job to iterate test report JSON to generate list of test cases executed and their results

Related to https://gitlab.com/gitlab-org/quality/team-tasks/issues/187

Should we just add one more job in our QA pipelines to parse the JUnit Test Report JSON and create/update the issues in this repo?

Or should this be a standalone job running periodically?

I think running them as part of the pipeline is a better choice - We need to be careful not to keep any upstream job (if any) waiting for too long.
