Comment 3 for bug 1833594

According to doc[0], add a registry as "*" may do the work:

     [plugins.cri.registry]
      [plugins.cri.registry.mirrors]
        ...
        [plugins.cri.registry.mirrors."*"]
          endpoint = ["http://34.235.169.214:5000"]
        ...

The `*` is registry host, which is also image prefix, it will match any image.
