This is a step for Life Cycle, in which admins can manually decide for every course, whether the course should proceed or roll back.
This is meant as a safeguard, so that admins can check whether their workflows are working correctly.
Each cron-job, all courses that are processed in a adminapprove step get added to the corresponding step table and the admin is notified.
If the admin marks courses to be proceeded / rolled back, they are removed from the step table and they are proceeded / rolled back during the next cron job.
