So it turns out this is the default behavior by argparse.

Specifying an option more than once with the default action='store' just
stores the last occurrence, see:

http://stackoverflow.com/questions/12461087/detecting-if-any-command-
line-options-were-specified-more-than-once-with-optpars

If we wanted a list, we'd use action='append' but that's not what we
want.

I think the default of action='store' to allow multiples but ignore all
but the last seems weird, but maybe argparse has never fixed that since
it'd break a default behavior, and thus probably a lot of scripts.

If you wanted to enforce this in novaclient, it sounds like you have to
write your own Action class which enforces that only one option is
specified.
