BVS-2510 example configuration for cloud stack deployment

This is a little confusing. Why are there separate bonds for storage and public? I don't think an interface can even be a member of multiple bonds can it? 

Shouldn't it be something like storage_vlan, management_vlan, etc? Then each one of those would ask for the parent interface, which would be a bond.

```yaml
bond_interface:
    interfaces: eth1, eth2
    name: bond0
public_vlan:
    interface: bond0
    vlan: null
storage_vlan:
    interface: bond0
    vlan: 7
manage_vlan:
    interface: bond0
    vlan: 6
    ip_address: 10.10.10.1/24
