    Support configuration of greenthreads pool for WSGI.

  - Operators may want to tune the ``max_overflow`` and
    ``wsgi_default_pool_size`` configuration options according
    to the investigations outlined in this `mailing list post
    <http://lists.openstack.org/pipermail/openstack-dev/2015-December/082717.html>`_.
    The default value of ``wsgi_default_pool_size`` inherits from
    that of oslo.config, which is currently 100.  This is
    a change in default from the previous Neutron-specific
    value of 1000.
