 * Configurable external gateway modes extension model.  By default, when a gateway is attached to a router using the Neutron L3 extension,
 * Network Address Translation (NAT) is enabled for traffic generated by subnets attached to the router. With this extension, the user will 
 * have the option of choosing whether SNAT should be enabled or not on a router basis.
