Document artifacts for Stargate/IBFE

This template is ONLY used for enhancement requests. Bug reporting or new feature request issues should use the other template options for issue submission.

Current Behavior

We currently just bundle everything together into the tar that Iron Bank serves, but as we expect Stargate to ingest these, we need to standardize the files/justifications/bill of materials/parent image materials so that this tar is essentially an API for others to interact with the CHT pipeline.

Purpose

Standardize how these artifacts are interacted with

Plan

• copy existing artifacts as appropriate by renaming, while leaving the existing files in place so that IBFE and VAT can modify their projects at their leisure
• decide on what new files to include, such as our new hardening manifest
• Convert files as appropriate (excel to csv, etc)

Acceptance Criteria

• tar is updated
• API spec documented
