Agent creates NH with 0.0.0.0

[Praveen]

On executing "service supervisor-restart", agent is creating tunnel-nh with destination-ip 0.0.0.0

[Praveen (praveen-karadakal)]

When OVS Peer adds routes, it does not set the server_ip_ field in the
AgentPath. Further when route is rebaked, the AgentPath module uses the
server_ip_ field to create the NH. This can result in NH being created
with dest-ip=0.0.0.0

Fix tunnel-dest IP being set to 0.0.0.0

When OVS Peer adds routes, it does not set the server_ip_ field in the
AgentPath. Further when route is rebaked, the AgentPath module uses the
server_ip_ field to create the NH. This can result in NH being created
with dest-ip=0.0.0.0

Fix:
1. Modified ChangeNH() to pick the dest-ip and store in server_ip_ field of
AgentPath.

Additional changes:
1. server_ip_ was a misnomer. Its renamed to tunnel_dest_
2. UT to verify the scenario
