Maru Newby 1105782e39 Reorganize unit test tree
This change ensures that the structure of the unit test tree matches
that of the code tree to make it obvious where to find tests for a
given module.  A check is added to the pep8 job to protect against
regressions.

The plugin test paths are relocated to neutron/tests/unit/plugins
but are otherwise ignored for now.
