Code review comment for lp:~allenap/maas/non-django-database-test

Looked through the code and I am still some what confused? What is legacy tests? I assume those must run as well when doing "make test"?

Looking at the code it was hard to see the difference between a legacy test and a none legacy test. Also no documentation on when legacy should be used over a standard test type. Is this something where we need to do work on tests that use legacy to remove this new "test.region-legacy"?
