Run tests in random order

[gforcada]

I created this job: https://jenkins.plone.org/view/Experimental/job/Shuffle%20tests (it boils down to bin/test --shuffle).

On the first run we manage to create a stackoverflow! 🔥 https://jenkins.plone.org/view/Experimental/job/Shuffle%20tests/1/console

On the second run only 4 test failures: https://jenkins.plone.org/view/Experimental/job/Shuffle%20tests/2/console

I set it to run once a week.

Is there anything else that we should do here? Send email to someone? 🤔

Yes, someone should attend to everything it finds. So we need to find someone interested in the quest and to have that person notified.

As for the run itself, it is doing exactly what that one should do.
