It turns out that nova-api and nova-metadata only depend on spawning
threads via scatter-gather. The scatter-gather already supports both
eventlet and threading mode so we can switch these services.
Our WSGI services (nova-api, nova-metadata) are not relying on
oslo.service to fork worker processes, but expect the web server to
handle that (uwsgi, apache mod_wsgi). This means we don't need to handle
any forking issues as no nova code runs before the fork.
