[OVS] Remote_ips for tunnel ports are not configured properly in case of
multipel physical networks
Steps to reproduce:
==============
1.Bring up CS in advanced zone with xen cluster with min of two hosts
and two nics on both the hosts
2.Create two physical networks with GRE isolation during zone creation:
in physical network1 add guest,public&management traffic types with tag "tag1"
in physical network2 add only guest traffic with tag "tag2"
3.create two network offerings NO1&NO2 with virtual networking and ovs as the
connectivity service provider and user taggings tag1 & tag2 in NO1 & NO2
respectively
4.Create isolated networks nw1 & nw2 using NO1 & NO2
5.Deploy vms in both the netwoks and make sure that both the networks are
spread across both the hosts in the cluster
6.Verify tunnel ports remote_ips on both the hosts
On xenservers used NIC0 for physical network1(by using traffic labels) and NIC1
for physical network2
NIC0&NIC1 both have routable IP addresses.
Result:
=====
Remote_ips for all the tunnel ports created in the above networks are set to
NIC1 ip addresses. But tunnel ports in network created on physical network1
should have NIC0 ip address as remote_ip and NIC1 ip address for the tunnel
ports in other network.

Here management label is on NIC0 and gre is on NIC1 and
10.147.42.13&10.147.42.14 are assigned to NIC1 on the hosts.
But in the above table we are using same ip address against bot the labels. So
tunnel ports for both the networks are created with same remote_ip address.
Host details are as follows:
mysql> select
id,name,private_ip_address,public_ip_address,data_center_id,cluster_id from
host where id in (1,2);
+----+-----------------+--------------------+-------------------+----------------+------------+
| id | name | private_ip_address | public_ip_address |
data_center_id | cluster_id |
+----+-----------------+--------------------+-------------------+----------------+------------+
| 1 | Rack1Pod1Host13 | 10.147.40.13 | 10.147.40.13 |
1 | 1 |
| 2 | Rack1Pod1Host14 | 10.147.40.14 | 10.147.40.14 |
1 | 1 |
+----+-----------------+--------------------+-------------------+----------------+------------+
2 rows in set (0.00 sec)
10.147.40.13& 10.147.40.14 ip addresses are management addresses assigned to
NIC0 on both the hosts.
Tunnel ports details on the hosts are:
