I noticed a todo tag, but didn't see any related restore resource cleanup, so I created this pull request.

thanks for your pr, but there's an issue with this implementation. DeleteRestoreCR is defined on a single rebuildFrom struct. According to the API definition, it should only delete the corresponding restore, not overreach and clean up all restores. I'm closing this PR for now, and we can address it later when there's a real user scenario.
