Juan Antonio Osorio Robles 7da4e498d4 apache wsgi: Exchange defaults for workers and threads
Due to Python's GIL [1], we can't use multiple threads for running
OpenStack services without a performance penalty, since the execution
ends up serialized, which defeats the purpose.

Instead, we should use several processes, since this approach doesn't
have this limitation.
