Remove BGP process completely.

        Args:
            vrf (str): The VRF for this BGP process.
            rbridge_id (str): The rbridge ID of the device on which BGP will be
                configured in a VCS fabric.
            callback (function): A function executed upon completion of the
                method.  The only parameter passed to `callback` will be the
                ``ElementTree`` `config`.

        Returns:
            Return value of `callback`.

        Raises:
            None
