Modify L3 Agent for Distributed Routers
This patch is an enhancement to the existing L3 Agent.
This allows the L3 Agent to support distributed routers
by enhancing the router object to function across
multiple nodes.
Utilized two new types of namespaces:
- FIP to handle multiple VM fips and routers per node
- SNAT to handle centralized SNAT per router
Rules and tables are enhanced and added to support routing
across distributed routers without going to a centralized
router.
Finally, a new configuration param 'agent_mode' is introduced
and it controls what the L3 agent can do: the available values
are: 'legacy', 'dvr', 'dvr_snat' (more details inline).
The l3-scheduler uses the newly introduced agent_mode to
determine what L3 agent to select during the scheduling
process.

I think this feature should be documented in the HA guide as well as in the config-ref.
