Currently there's a cron job in a teuthology VM running a script to find all trackers in needs-backports and to create their corresponding backport trackers. This is done through the [Backport Bot](https://tracker.ceph.com/users/12172) Redmine account.
This PR intends to run this cron job task as a periodic Github Action.
