    [Fullstack] Limit number of Neutron's api workers

    Default number of api workers in Neutron is set to be equal to
    number of CPU cores on host. That is fine on production environment
    but on fullstack tests, where each test spawns own neutron-server
    process it might cause host overload.

    This patch limits number of api_workers to 2 which should be enough
    for single test case and should make significantly lower load on host.
