ci: Separate parallel vs sequential tests

Browse Source 
In order to differentiate tests that can be run in parallel versus
tests that must be run on their own, we move all tests into dedicated
modules.

The point is to avoid glitches in results that can be caused by the fact
that other tests (hence VMs) are running at the same time.
