util.async: Add sleep() method with configurable scheduling backend No scheduler set by default, so it will error (we plan to initialize it in util.startup). We wanted to avoid a hard dependency on util.timer (which in turn depends on network backends, etc.), and we didn't add timer.sleep() because we didn't want to add a hard dependency on util.async for things that don't need it.
