breaking down tests.py into smaller pieces

tests.py is currently at ~5500 lines of code, it's
time to break it down into smaller files.

I started with an easy middleware set of tests
(i.e., versioned writes, ~600 lines of code ) so I can get
some feedback. There are more complicated tests that cover
multiple middlewares for example, it is not so clear where
those should go.
