This fix adds support for image registries that expect authentication for POST /v2/token such as used by the GET. E.g., JFrog Artifactory y has been observed to respond with a 401 (Unauthorized) in that case. Adding 401 in addition to the current handling of 405 and 404 in the resolver solves the authentication problem. Finally, this enables image pulls also for Artifactory.
