Could you elaborate a bit more, Yoan? The common.py module is supposed
to be extended with code common to all other modules in the
testbed_model package. Right now we only have MesonArgs which fits in
common.py, but we could also move something else into common.py. We
also could rename common.py to something else, but then the above
purpose would not be clear.

I'm finishing the docstrings soon so expect a new version where things
like these will be clearer. :-)
