I renamed the mode ci-pipeline to ci-pipeline-duration. After that I introduced a new mode ci-pipeline-status which checks the pipeline status. All possible states (https://docs.gitlab.com/ee/api/pipelines.html) were mapped. The most states should never happen. "msg" 's are defined for my use-case and could be modified if they doesn't match to other cases.
