Public bug reported:

Currently, main class for L3, FWaaS and VPNaaS is following.

                 -----------
                 |L3NATAgent|
                 -----------
                       |
                       |
            --------------------------
            |L3NATAgentWithStateReport|
            --------------------------
             |                      |
             |                      |
       -----------               ---------
      |L3WithFWaaS|              |VPNAgent|
       -----------               ---------

* When launching l3-agent without FWaaS, L3NATAgentWithStateReport  class is initialized.
* When launching l3-agent with FWaaS, L3WithFWaaS class is initialized.
This is achieved by following commit. 
https://github.com/openstack/neutron-fwaas/commit/debc3595599ed6cd52caf6e04f083af9c93f6fa4

* When launching vpn-agent with/without FWaaS, VPNAgent class is initialized.
  In this case, L3WithFWaaS class is not initialized even though FWaaS is enabled.
  Thus, FWaaS won't be available when using both of FWaaS and VPNaaS.

Here is log of vpn-agent that is when the agent receives RPC request about firewall from neutron.
