Automate release manager group membership
The new workflow for onboarding release manager trainees should be this:
- Trainee edits
config/release_managers.yml
, adding their name and username(s) - Trainee opens a merge request with the changes
- MR gets accepted by release coordinator
- Manual CI job is run to perform the sync
Offboarding is similar:
- Release coordinator removes person from configuration file
- Manual CI job is run to perform the sync
