Be able to execute the same paths CI runs but locally if you have the resources to do so.

Describe the solution you'd like

We now have make unittests to run everything but itests, we should have a make itests to do the itests. I'm not sure if a make test is a good idea though, we don't really want to give the impression this is a good idea for any contributor to run (maybe it could print documentation though).

Currently itests are each run separately, and they are configured independently in the CI config. It would not be ideal to have yet another place to have to remember to add your new itest to make it run, so some deduplication is needed. Either the Makefile target reads CI config (new GitHub Actions one) to figure out what and how to run, or we make CI config and Makefile depend on some new configuration, perhaps a text file in the itests directory, or perhaps we decorate itests in source and extract metadata from there.

Describe alternatives you've considered
