-------------------------------------
Hi [~pnowojski], I test the pr of FLINK-24344 just now. It make IOException
thrown by
_*CheckpointStorageCoordinatorView#initializeLocationForCheckpoint(long
checkpointId)*_ reaches _*CheckpointFailureManager*_, thus it make
tolerableCheckpointFailureNumber can effect. But it still does not count
failures into numberOfFailedCheckpoints.
A common use case is to configure a relatively large
tolerableCheckpointFailureNumber to prevent the job full restart, still want
aware _*CheckpointStorageCoordinatorView#initializeLocationForCheckpoint(long
checkpointId)*_ through metric of numberOfFailedCheckpoints.

> h1. *Problem*
> In current implementation, checkpoints failed in trigger phase do not count
> into metric 'numberOfFailedCheckpoints'. Such that users can not aware
> checkpoint stoped by this metric.
> As lang as users can use rules like _*'numberOfCompletedCheckpoints' not
> increase in some minutes past*_ (maybe checkpoint interval + timeout) for
> alerting, but I think it is ambages and can not alert timely.

> h1. *Proposal*
> As the title, count checkpoints failed in trigger phase into
> 'numberOfFailedCheckpoints'.
