Refactore the Load Balancer Controller

Remove useless controllers , such as zone, node,etc.
The api is introduced to describe the objects in the load balancer, for example eip, lb, listener, backend etc.
Fix some issues, such as yunify#101, yunify#98, yunify#81, yunify#63
Fix incorrect vip display when there are multiple private ip's.
