    Add a new native function that resolves docker image names into more
    specific forms.  In particular, it can look up a docker registry and
    convert image:tag to image@digest at jsonnet-eval time.
    Limitations: Does not currently support private docker
    registries (that require authentication).
    Controlled via two new command line flags:
    - `--resolve-images` Change implementation of resolveImage native
      function. One of: noop, registry (default "noop")
    - `--resolve-images-error` Action when resolveImage fails. One of
      ignore,warn,error (default "warn")
    Note in particular that the defaults will *not* do remote registry
    lookups, and will only add an explicit ":latest" tag where no tag was
    Fixes #13
