[SPARK-13965] [CORE] Driver should kill the other running task attempts if
any one task attempt succeeds for the same task
## What changes were proposed in this pull request?
core\src\main\scala\org\apache\spark\scheduler\TaskSetManager.scala
TaskSetManager kills other running attempts when any one attempts succeeds
for the same task.
## How was this patch tested?
I have verified this patch manually by enabling spark.speculation as true,
when any attempt gets succeeded then other running attempts are getting killed
for the same task and other pending tasks are getting assigned in those.
