> During the consumer group rebalance, when the joining group phase finishes,
> the heartbeat delayed operation of the consumer that fails to rejoin the
> group should be removed from the purgatory. Otherwise, even though the member
> ID of the consumer has been removed from the group, its heartbeat delayed
> operation is still registered in the purgatory and the heartbeat delayed
> operation is going to timeout and then another unnecessary rebalance is
> triggered because of it.
