Environments Cleanup
DRI: @shinya.maeda ## Problem Stale/stopped environments build up over time. The old environments don't offer value to the user, they clutter the UI, and in the worst-case scenario, can lead to [outages](https://gitlab.com/gitlab-com/gl-infra/production/-/issues/5068). ## Proposal Provide tools and documentation so users can manage/archive/delete environments that are no longer useful for them. ### Some specific approaches 1. Clean up stopped environments automatically with sane defaults 1. Make timing of removal configurable?
