I am leaning towards utilizing pulp_file for uploading/downloading tarballs and then pulp_ostree for importing/parsing the uploaded/downloaded tarballs. The tarballs should be passed to the import-all function via content_href instead of artifact_href. Also, this would require us to update the CLI.

Later, we should completely deprecate the use of artifacts since they should be transparent to users.

+1 to it.
