Shall we also add a `scheduleRunAsync` method where we allow to pass a
`TimeUnit` argument for convenience?

> It is a common pattern to schedule a call to be executed in the future.
> Examples are
> - delays in retries
> - heartbeats,
> - checking for heartbeat timeouts
> I suggest to add a {{scheduleRunAsync()}} method to the {{RpcEndpoint}}.
