Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server, Network Controller
Affects Versions: 4.4.0
Environment: Latest build from 4.4 with commit

Reporter: Sanjeev N

Priority: Critical
Fix For: 4.4.0
[OVS] Tunnel ports are not getting deleted even failure in vm deployment
Steps to Reproduce:
================
1.Bringup CS in advanced zone with Xen cluster
2.Create physical network with GRE isolation
3.Create network offering with virtual networking and ovs as the connectivity
service provider.
4.Deploy vm with above offering and simulate vm failure
(In my case I was trying with multiple physical networks scenario and because
of some configuration issues network implement failed so failure in vm
deployment)
Result:
=====
During vm deployment ovs bridge and tunnel ports were created between the two
hosts. But after the failure there was no clean up of the ovs-bridge and the
tunnel ports.
Observations:
==========
xapi7 and xapi6 were the bridges created for the network.
Following is the log snippet from ovstunnel log from both the hosts:
