示例1: ImagePull
// ImagePull requests the docker host to pull an image from a remote registry.
// It executes the privileged function if the operation is unauthorized
// and it tries one more time.
// It's up to the caller to handle the io.ReadCloser and close it properly.
//
// FIXME(vdemeester): there is currently used in a few way in docker/docker
// - if not in trusted content, ref is used to pass the whole reference, and tag is empty
// - if in trusted content, ref is used to pass the reference name, and tag for the digest
