Build Update for alauda/ovn
-------------------------------------

Build: #2
Status: Passed

Duration: 19 mins and 3 secs
Commit: ff3e117 (branch-20.06)
Author: Numan Siddique
Message: ovn-northd: Add ARP responder flows for SNAT entries.

If the below SNAT entry is added:
ovn-nbctl lr-nat-add snat 172.168.0.120 10.0.0.5

And when the logical port with IP - 10.0.0.5, sends a packet destined to
outside, gets SNATted to 172.168.0.120 as expected, but for the reverse traffic
if the upstream switch sends an ARP request for 172.168.0.120, then OVN doesn't
reply and the reply traffic never reaches the logical port.

This patch fixes this issue by addding ARP responder flows for SNAT entries.

Note that, if 172.168.0.120 happens to be the logical router IP, then it works.
