> Current EIP in CloudStack has below semantics.
> - When a user VM is deployed, a public ip is automatically acquired. This IP is owned by the vm's account and is marked as 'system' in the db.
> - When the user VM starts, static NAT is provisioned on the static NAT provider between the public ip and the guest ip of the vm.
> Since public IP's can be scarce resource is some deployments, its not desirable to allocate a public IP by default. This bug is to provide the flexibility for cloud providers to enable/disable the ability to automatically allocate public IP.
