> Add the statistics of pending checkpoints as a gauge metric. When the checkpoint appears not to be completed, this metric would  help to get the state of a pending checkpoint , e.g  which task did not complete the checkpoint. 
> The statistic will be as the follows：
> checkpointID, 
> Number Of Acknowledged Tasks,
> Number Of Not yet Acknowledged Tasks, 
> The detail of not yet acknowledged JobVertexID, taskID
