1. As "List" method of artifact DAO doesn't return the artifacts that referenced by other and without tag, so we introduce a new method "GetByDigest" to check the existence of artifact
2. The "Www-Authenticate" header is needed to be returned when the request is unauthorized. This is required in the OCI distribution spec and is needed when pushing CNAB
