[SPARK-8273] Driver hangs up when yarn shutdown in client mode

In client mode, if yarn was shut down with spark application running, the application will hang up after several retries(default: 30) because the exception throwed by YarnClientImpl could not be caught by upper level, we should exit in case that user can not be aware that.

The exception we wanna catch is [here](https://github.com/apache/hadoop/blob/branch-2.7.0/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/io/retry/RetryInvocationHandler.java#L122), and I try to fix it refer to [MR](https://github.com/apache/hadoop/blob/branch-2.7.0/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-jobclient/src/main/java/org/apache/hadoop/mapred/ClientServiceDelegate.java#L320).
