Bug Description
The l2-pop mechanism driver uses an ARP responder to avoid ARP broadcast but it only works with the LB agent.
We need to implement an ARP responder for the OVS agent also.

Implement local ARP responder onto OVS agent
With ML2 plugin and l2-pop mechanism driver, it's possible to locally
answer to the ARP request of the VM and avoid ARP broadcasting emulation
on overlay which is costly.
When this functionality is enabled, the OVS flows logic evolves to [1].
This functionality was introduce in 2.1 OVS branch [2].
A README is added to describe l2-pop mechanism driver and the agents
