public IClientManager<TEndPoint, SyncPipeConsensusServiceClient> getGlobalSyncClientManager() {
    return this.syncClientManager;
  }
This class is used to hold the global component such as syncClientManager and asyncClientManager
used by pipeConsensus. The purpose of designing this class is that both the consensus layer and
the datanode layer of pipeConsensus use clientManager.

<p>Note: we hope to create the corresponding clientManager only when the consensus is
pipeConsensus to avoid unnecessary overhead.
