In #20538, I was asked to consider refactoring the new OCI pull code from within the generic machine directory. This is something I had tried when originally coding it but it became apparent that a much larger refactor to prevent circular deps was needed. Because I did not want to pollute the initial PR with that refactor, I asked for the PR to merge first. This is the refactor that needed to be done. Signed-off-by: Brent Baude <bbaude@redhat.com>
