Does this create a need to change or add documentation? Did you do so? No

Testing performed, if any:

Those two Python scripts could actually be used in a GitHub workflow to check that testlist_clm.xml is well-formed... Will play with this but won't let it hold up this PR. @ekluzek

I verified that the new testlist only has izumi_nag. And the changes all make sense to me. Some things I hadn't thought about you also brought in which makes sense. This will make the test list on Derecho, slightly longer, but that's fine.

I also think that the tools you made should become more mainstream. The tmp directory makes me think you were going to delete them. But, I don't think you should. We should do more of using tools like this. If they do become more mainstream, I'd like to see more testing for them, and probably a library level that removes some code duplication.

But, I think you bring this in like it is.
