gongysh a7e73f15c1 l3 agent rpc
On one hand, we sync router data (including routers,
their gw ports, interfaces and floatingips) from l3_agent
to quantum server periodically if needed.

On the other hand, we notify l3 agent from quantum server when
we delete or update a router's stuff, such as floating IP,
interface and gwport and router itself.
