[SPARK-30387] Improving stop hook log message
### What changes were proposed in this pull request?
ShutdownHook of YarnClientSchedulerBackend prints just "Stopped" which
can be improved to "YarnClientSchedulerBackend Stopped" for better
understanding.
### Why are the changes needed?
While stopping or gracefully exiting the spark-shell/spark-sql --master
yarn, only printing `stopped` is useless.
### Does this PR introduce any user-facing change?
Yes. Log info message change.
### How was this patch tested?
Manually
Closes #27049 from jobitmathew/imp_stop_message.
