This makes the structure simpler and in line with all other nodes. * Create OpenMessagesTracker to simplify tracking open messages in SourceNode and DestinationNode. * destination acker tests * use cerrors.New * use LogOrReplace * use LogOrReplace * make signal channel buffered * improve benchmarks * fix linter error * add comments * simplify implementation * update semaphore * update param name * remove redundant if clause * make it possible only to inject control messages * improve destination acker caching test * remove TODO comment * update comment
