The next version is only depending on pycotap now. I'm installing it in the 
venv there that we also install when running the old avocado tests. Not sure 
whether that's the best solution, though. Would it be OK to have it in 
python/wheels/ instead?

As I'm mentioned elsewhere, the tests that really have a hard dependency on 
the Avocado framework are only the tests that use the cloud-init images via 
the LinuxTest class. That's currently onle these files:

- boot_linux.py
- hotplug_blk.py
- hotplug_cpu.py
- intel_iommu.py
- replay_linux.py
- smmu.py

I assume we could continue using avocado.utils for the cloud-init stuff 
there, and just run them via the meson test runner, too. I'll give it a try 
when I get some spare time.
