FloatingIP (DNAT) distribution

Registered by Eran Gampel

Allow for FIP distribution for Compute host with external network gateway port.
In the current implementation FloatingIP (DNAT) translation done at the Network Node in a centralize way creating extra latency, bottleneck and introducing SPOF. This blueprint intend to support FIP traffic to be sent directly to the external network without going through the network node while preserving the centralize solution for Compute host that are not connected to the external network directly.
For network segment that need direct access to the public network this could improve scalability and remove the network node bottleneck and SPOF.
Deployment of the web tier can be done using the nova zone to distinguish the compute hosts with additional external network port.
