1.6.Z of containerd supports token refresh. I'm probably missing some mechanism here, but when I force oc-mirror to use this bumped registry repo (via replaces in go.mod) -- even with no code changes to hook the token refresh handler -- I'm seeing the token refreshed in response to a 401 authorized status from the to-be-mirrored registry.

And the same test for oc-mirror results in a continuous stream of 401s which make it terminate.
