Previously, we used the docker config digest (also called "image ID" by Docker) for the value of the `ImageID` field in the container status. This was not particularly useful, since the config manifest is not what's used to identify the image in a registry, which uses the manifest digest instead. Docker 1.12+ always populates the RepoDigests field with the manifest digests, and Docker 1.10 and 1.11 populate it when images are pulled by digest. This commit changes `ImageID` to point to the the manifest digest when available, using the prefix `docker-pullable://` (instead of `docker://`)

can you check if we also needed upstream 29316 which we pulled previously, or is it already in? |

Evaluated for origin test up to 8a78ecf |

noting that 29316 is already in, so this is sufficient. LGTM |
