Zane Bitter a69431ab6c Make ResourceDefinition round-trip stable to avoid extra writes ... The part of a ResourceDefinition that lists explicit dependencies was not round-trip stable. As a result, when we copied a new resource definition into the existing template during a stack update, we would end up rewriting the template unnecesarily (i.e. even though we check for changes) every time if depends_on was not specified in the resource originally. At the end of each update, we write the new template to the DB in its entirety, which removes these extra lines again, ensuring that we will experience the same problem on every update. This was causing a *lot* of unnecessary writes. This change ensures that the definition remains stable across a round-trip, so that no unnecessary changes appear in the template.
