## What is the purpose of the change
Before this PR, `CHECKPOINT_EXPIRED` is not counted in
`continuousFailureCounter`. Hence,
if the failure of checkpointing is detected after checkpoint times out, the
failure get ignored since
the `PendingCheckpoint` has already been discarded, leading the job unable
to restart automatically in theory
unless something else fails.
This PR counts `CHECKPOINT_EXPIRED` in `continuousFailureCounter`.
