In previous releases, the /etc/init.d/neutron-vpn-agent script did not contain a reference to /etc/neutron/l3_agent.ini. At the same time, the Networking service packages did not provide a sample init script for FWaaS. These prevented VPNaaS and FWaaS features from being used with Networking service init scripts.
This fix ensures that deploying the Networking service will also:
* add a reference to /etc/neutron/l3_agent.ini in /etc/init.d/neutron-vpn-agent,
* install a sample init script for FWaaS, i.e. /etc/neutron/fwaas_driver.ini, and
* add a reference to /etc/neutron/fwaas_driver.ini in /etc/init.d/neutron-l3-agent.
With this, VPNaaS and FWaaS features can now be configured and used properly with Networking service init scripts.
