> Fix For: 3.3

>
> When we schedule the event for processing the broker heartbeat request in
> QuroumController, we do not give a deadline. This means that the event will
> only be processed after all other events which do have a deadline. In the
> case of the controller's queue getting filled up with deadline (i.e.,
> "deferred") events, we may not process the heartbeat before the broker
> attempts to send another one.
