[BUG] Problem with multi-arch images

[usrbinkat]

Container Data Importer seems to be unable to handle multi-arch manifests.

We should investigate:

• [ ] Any possible issues in our build/publishing method
• [ ] Investigate CDI implementation to determine if CDI has the mechanics required to parse manifests
• [ ] Report issue to the Kubevirt mailing list to evaluate opportunity for remediation

Notes:

• observed multi-arch image works properly when using containerdisk (no CDI)
