Currently there isn't the rt cgroup attrs still haven't been
implemented, because the kernel side interface is so awful, and is about
to get changed.
Best is probably to write these bits out from ExecStartPre= or so, and
use "%r" to get the cgroup path. But it's really nasty, since it isn't
clear what to write in there, and you'd have to iterate it up the tree, manually.
