Add LUKS discard and open_options fields from https://github.com/coreos/ignition/pull/1540. Also, users might reasonably want to enable discard for rootfs LUKS, so add it to the boot_device sugar. Don't add an open_options field there, since the sugar isn't meant to provide that level of customization.
