We currently only have one app callback for vNIC creation and destruction. This is insufficient, because some actions have to be taken before netdev is registered, after it's registered and after it's unregistered. Old callbacks were really corresponding to alloc/free actions. Rename them and add proper init/clean. Apps using representors will be able to use new callbacks to manage lifetime of upper devices.
