What happened?

While attempting to use the oc-mirror tool, it became apparent that registry credentials must be stored in the {XDG_RUNTIME_DIR}/containers/auth.json location. I think it would be useful to have an option for specifying an auth file location (similar to how podman does it).

What did you expect to happen?

Having an option to specify an auth file.

How to reproduce it (as minimally and precisely as possible)?

$ oc-mirror --help

Anything else we need to know?

Just a feature request, no current issue
