public interface PriorityMessage
```
INTERNAL API Messages marked with this trait will be sent before other messages when buffering is active. This means that these messages don't obey normal message ordering. It is used for failure detector heartbeat messages.
In Artery this is not used, and instead a preconfigured set of destinations select the priority lane.
