Thanks. Do you think it'd make sense to also add one of these for
kunit.action (i.e., support for listing tests/test attributes)?

Otherwise, other than maybe the possibility of adding some detail to
the help texts (though that'd just duplicate what's in the
documentation for those module parameters), this looks good. We can
always add more in a follow-up if it's useful.
