[SPARK-24795][Core][FOLLOWUP] Kill all running tasks when a task in a
barrier stage fail
## What changes were proposed in this pull request?
Kill all running tasks when a task in a barrier stage fail in the middle.
`TaskScheduler`.`cancelTasks()` will also fail the job, so we implemented a new
method `killAllTaskAttempts()` to just kill all running tasks of a stage
without cancel the stage/job.
