Add support for new libnetwork API calls:

/NetworkDriver.ProgramExternalConnectivity
/NetworkDriver.RevokeExternalConnectivity

    // ProgramExternalConnectivity invokes the driver method which does the necessary
    // programming to allow the external connectivity dictated by the passed options
    ProgramExternalConnectivity(nid, eid string, options map[string]interface{}) error

    // RevokeExternalConnectivity aks the driver to remove any external connectivity
    // programming that was done so far
    RevokeExternalConnectivity(nid, eid string) error

Can we also utilize this for routing to external networks (i.e., using Neutron routers perhaps)?
