Code Issues Proposed changes

Add support for running neutron api by httpd+mod_wsgi

Browse Source 
This change allows users to run neutron api by httpd+mod_wsgi with
an independent rpc worker service. Setting service_name to httpd is no
longer supported, because it results in incomplete deployment without
rpc services.

features:
- |
Now ``neutron::server::api_service_name`` can accept and handle ``httpd``
as a valid service name, to run api service by httpd+mod_wsgi.
upgrade:
- |
The ``neutron::server::service_name`` parameter no longer accepts
``httpd`` as a valid service name. To run api service by httpd,
the ``neutron::server::api_service_name`` parameter should be used instead
along with the ``neutron::server::rpc_service_name``.
deprecations:
- |
Usage of arbitaly service name for the ``neutron::server::service_name``
has been deprecated and will be removed in a future release.
