> Checkpoint statistics contain the duration of a checkpoint, measured as from the CheckpointCoordinator's start to the point when the acknowledge message came.
> We should additionally expose
>   - duration of the synchronous part of a checkpoint
>   - duration of the asynchronous part of a checkpoint
>   - number of bytes buffered during the stream alignment phase
>   - duration of the stream alignment phase
> Note: In the case of using *at-least once* semantics, the latter two will always be zero.
