Support loading and saving tarballs with more than one image. Add a new `/libpod/images/export` endpoint to the rest API to allow for exporting/saving multiple images into an archive. Note that a non-release version of containers/image is vendored. A release version must be vendored before cutting a new Podman release. We force the containers/image version via a replace in the go.mod file; this way go won't try to match the versions. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
