Add test bindings for Python
Add test bindings for Python

The bindings read specially-crafted JSON and run HyperDex commands,
checking for the expected result.  Although only supported for Python at
the moment, the intent is to write universal client-side tests that can
easily be run against any new language just by writing a new bridge.
