network parity: enable nova-network NAT/gateway

Registered by Brad Hall on 2011-10-26

Goal is to be able to leverage the same NAT gateway capabilities that are provided by the VlanManager, but in a way where such a gateway exists on a Quantum network.

This capability will be limited to network created using nova-manage, and will only work for quantum networks with non-overlapping IP addresses (as was the case with the original VlanManager).

Similar to how we implement the nova-parity DHCP feature, we will use the linux_net vif-plugging capability to plug interfaces on the network node into a Quantum network.
