Container Registry: Delete Images/Packages after merge
Problem to solve
Users that utilize the CI pipeline create many images as part of the build process. These images often go unused or are used once, thus taking up space in the registry with no value add.
As an insight gathered from interviews: uxr_insights#562 (closed) users reported no value in an archive of images/tags created on auxiliary (non-master) branches after the branch has been merged.
Users are reporting that their registry size is factor they need to consider when managing their overall project size.
When submitting an MR, an option exists to delete the branch after the merge request completes. I propose we add a second check box option to delete branch specific images/packages.
