Such tool mostly already exists in ovirt sdk examples:

So for rhv-upload there is no use case for standalone script.
Sure, not right now, but what I'm saying is that a standalone imageio
plugin would be possible.

But today we require the plugin name in nbdkit command line:
./nbdkit -f -v python zero.py
It could be nice to be able to do:
./nbdkit -f -v zero.py
No need because with shebang scripts you can do:
./zero.py [-f] [-v] [params ...]
and for Python plugins this works today. (It doesn't work with
nbdkit-sh-plugin.)
