* streamLayeredImage: self-document the script
'podman load' doesn't let me override the name/tag from the image.
This name and tag is dynamic and in a CI environment so I would like to
be able to adjust the tag dynamically.
Since the image is streamed by stream_layered_image.py, there is no need
to stick with the nix-hardcoded image name/tag: the python script can
accept another name
I've added argparse to expose the feature. It has the added benefit of
adding `--help` support to the script, which makes its usage
self-explanatory.
