Tobias Urdin bb54858824 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.
