app.image.pull
==============
`image` is the name of the image to pull. Format for the name is "registry/repo/image:v1.2.3" where registry may be omitted and it will default to docker registry in this case. It can or cannot contain the tag - this will be passed as is to docker so this should be analogous to what `docker pull` expects.
`auth_config` should be specified if image to be retrieved is under a private repository.
