- What I did
This PR add the possibility to use short id in docker app commands (app image tag , app image remove, app run...)

- How I did it
The bundle store interface now exposes a LookUp function which convert a string (an id, short id, tagged or digested reference) into a reference.Reference object if it exists in the store. A map of ID to []reference.Reference is also maintained by the bundle store implementation.

- How to verify it
Some unit tests and e2e tests have been added

- A picture of a cute animal (not mandatory but encouraged)

It seems that docker image inspect x works if you have only 1 image whose id is starting with x

if err != nil {
return nil, errors.Wrapf(err, "failed to read bundle %q", ref)
}

data, err := ioutil.ReadFile(filepath.Join(path, "bundle.json"))
bndl, err := b.fetchBundleJSON(filepath.Join(paths[0], "bundle.json"))

What happens to other paths here? Is it worth it returning all the paths if we only use the first (and I guess it has to be the id path?

…le store. Now the bundle store scans the bundle directory and creates a map of existing bundle references. All subsequent operations on the bundle store are using this map as the reference for stored bundle.
