PodVIFDriver base class defines activate_vif method, which currently accepts two arguments - pod and vif. While vif argument is utilized for most of the time, pod is not. It was discovered during development, where there is a need for calling activate_vif method from within a CRD resource rather than pod. Change-Id: I6367bd93d5c0abe9a2ee6d018d997209f23f5318
