Add expected_hash to DataVolume #1520
Description
/kind enhancement
qemu images may be garbled en route from an http server to CDI's target. To identify this condition, many servers (e.g. Fedora provide the expected checksum of the image.
I would like to state the expected hash in the DataVolume spec, and have the import fail if any of the provided hashes does not match the imported data.
