harbor: docker.io proxy cache failing after V2.2 migration

docker pulling some images through the proxy cache does not persist them.

Expected behavior and actual behavior: Expected the images if they do not exist in proxy cache to be downloaded and persisted locally until deleted (by retain policy for example)

Steps to reproduce the problem: Setup docker.io proxy cache on harbor registry and pull through it: docker pull registry.foo.bar/docker.io/osixia/openldap:1.3.0

Versions: Installed with harbor-helm

dependencies:
- name: harbor
  version: 1.6.1
  repository: https://helm.goharbor.io

Same issue on v2.5.0-98e1b82f

Summary of this issue: the image tag is not guaranteed to be cached in Harbor, because it depends on the docker client’s behavior, if the tag/digest information is cached local, the docker client just sends a pull by digest request to the server, Harbor could not cache this image by tag, but cache it with digest.
