Fix the remote client to untag all tags of the specified image. Instead of querying the image on the client side, support the case where both, repo and tag, are empty and remove all tags. Reuse the ABI implementation where possible. In retrospective, the libpod untag endpoint should support a slice of strings to batch remove tags rather than reaching out for each tag individually. Enable the skipped test. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
