when creat loadbalancer listeners from openstack, there is no loadbalancerid in odl neutron,
the listeners in odl:
"listeners": {
"listener": [

{ "uuid": "7ecc6185-356e-4615-a2ac-f6a8cb5c600f", "tenant-id": "1292b071-c8fe-4626-bff1-39c360f6552a", "connection-limit": -1, "name": "Listener 1", "admin-state-up": true, "protocol": "neutron-constants:protocol-http", "protocol-port": 80 }

]
},

the reason is that, the received lb listener from openstack contains loadbalancers as xml key, not load_balancers.

so, in NeutronLoadBalancerListener.java, the XmlElement name of load_balancers should be changed to loadbalancers
