When using random names for artifacts like AWS snapshots, or Azure images, it becomes hard to clean them up in case of CI failure. See this issue for more details: https://github.com/osbuild/osbuild-composer/issues/942 This PR introduces predictable names so that we can easily determine which artifact belongs to which PR and therefore we can decide to wipe all resources that are not needed any more.
