I'd be ok with that in principle. It will requiring some separation of
self.ui.here which currently roots all lookups - both repo and config.
But, testr is going to learn about test profiles to deal with the need
to run the same tests in many environments - I'm going to tie it into
tox in some fashion.
The design of testr is to be a metatool, fundamentally different to
e.g. testtools which is very location-and-context specific.
