The old measurements.json (v1) was contain one set of measurements and had a path scoped for every CSP.
The new version is less structured, allowing for future extensions.
The version v1 of the image/info.json file is not capable to encode multiple regions and
attestation variants for a given csp.
This is why a v2 is needed with a more extensible structure.
* Merge measurements.image.json and measurements.json into latter.
* Use static (known) measurement values for the ones we cannot precompute.
