use docker image ID as value for version label about docker2aci

[philips]

I am thinking we should standardize some of these details from the conversion process. Here are my suggestions:

• appc.io/docker/v1/checksum
• appc.io/docker/v1/tag
• appc.io/docker/v1/repository
• appc.io/docker/v1/imageID
• appc.io/docker/v1/parentID

Something like this makes total sense to me

Seems like we should have a WELLKNOWN.md file with well-known labels or something.

We should loop in the quay.io guys here too, hmm?

We currently add:

{"name": "quay.io/derived-image", "value": synthetic_image_id},

where synthetic_image_id is the image ID we generate for the squashed image. This allows us to map any ACI we generate back to an image, and thereafter back to a repository and tag.
