This is a good start, but something we need to consider here, is all job / projects use base-minimal. So, adding per project setting here isn't going to scale well IMO. For this specific case, I think we can do a few things.

We should can create a new job, say awx-base, as untrusted, that is zuul-jobs. have it parent to base (which is also untrusted). Then, in the post-run logic, after log collections, we can add logic to clean up static nodes. In zuul, we've also discussed the idea of a clean up handler, but don't think it is landed.

2nd, we shouldn't be modifying base-minimal directly, we should first propose this to base-minimal-test, as not to break the world. Again, since everything uses this base job, we need to first properly ensure it is tested via base-minimal-test before promoting to base-minimal.
