Create VAT Response Attestation that Includes Image Lineage

VAT Response Attestation with Lineage

In order to maintain a complete record of a given image's VAT Response lineage that can be uploaded to the VAT to supply data for images that might not exist in each environment (or Impact Level) that a pipeline is running in, we must first update the harbor stage where we upload the VAT response. We need to add the VAT_RESPONSE generated by "this" pipeline run the vat_response.json created as part of #744 and upload this cumulative vat_response, which represents the full lineage of "this" image, including its own vat_response.
