This adds all the standard subcommands for the ImageRepository type.
Following `source`, I have put them under a namespace: `auto`,
referring to automation.
NB For `create` I use controllerutil.CreateOrUpdate, which looks to me
like a slightly more rounded version of the upsert* funcs.

This works around another bug on Windows platforms that would cause the
kustomize-controller to choke on the kustomization.yaml generated by the
bootstrap command due to the filepath being in a Windows format.
By using `filepath.Rel`, the output is _just_ the filename for files
relative to the bootstrap path, which is at the moment sufficient to
make it work.
