> [SDN] OVS bridge/tunnel ports are not getting deleted from Host even though there are no vms in the network
> Steps to Reproduce:
> ================
> 1.Bring up CS in advanced zone with two hosts in a cluster
> 2.Create physical network with GRE isolation
> 3.Create network with Connectivity service and OVS as the provider
> 4.Deploy couple of vms in the above network.
> 5.Migrate vms to one host and make sure that all the vms (including vr) are running only on one host
> 6.Verify tunnel ports on the host where there are no vms running
> Expected Result:
> ==============
> Tunnel ports and ovs bridge shall be deleted from the host where no vms are running
> Actual result:
> ===========
> OVS bridge and tunnel ports are still present even after migrating all the vms to another host in the cluster
> Observations:
> ============
> Following bridge info is from the host on with all system vms and guest vms are running
> [root@xen-host-13 ~]# ovs-vsctl list-br
> xapi0
> xapi1
> xapi2
> xenbr0
> xenbr1
> On the host where only guest vms are running
> [root@xen-host-14 ~]# ovs-vsctl list-br
> xapi2
> xenbr0
> xenbr1
> Before migration:
> ==============
> [root@xen-host-13 ~]# ovs-vsctl list-ports xapi2
> t997-1-2
> vif12.0
> vif13.0
> [root@xen-host-14 ~]# ovs-vsctl list-ports xapi2
> t997-2-1
> vif7.0
> After migration:
> =============
> [root@xen-host-13 ~]# ovs-vsctl list-ports xapi2
> t997-1-2
> vif12.0
> vif13.0
> vif15.0
> [root@xen-host-13 ~]#
> Following is the target host on which no vms are running:
> [root@xen-host-14 ~]# ovs-vsctl list-br
> xapi2
> xenbr0
> xenbr1
> [root@xen-host-14 ~]# ovs-vsctl list-ports xapi2
> t997-2-1
