* Exception thrown when the downstream service is changed by a pipeline
* reconfiguration. This exception was introduced so retrySend() in
* {@link QuorumPipelineImpl} could differentiate between normal termination of
* a service (which will interrupt the {@link HAReceiveService} and thus
* propagate a {@link CancellationException} to the upstream service) and a
* pipeline change which requires retrySend() to retransmit the message and
* payload from the leader along the reconfigured write pipeline.
