[SPARK-19718][SS] Handle more interrupt cases properly for Hadoop

## What changes were proposed in this pull request?

[SPARK-19617](https://issues.apache.org/jira/browse/SPARK-19617) changed `HDFSMetadataLog` to enable interrupts when using the local file system. However, now we hit [HADOOP-12074](https://issues.apache.org/jira/browse/HADOOP-12074): `Shell.runCommand` converts `InterruptedException` to `new IOException(ie.toString())` before Hadoop 2.8. This is the Hadoop patch to fix HADOOP-1207: https://github.com/apache/hadoop/commit/95c73d49b1bb459b626a9ac52acadb8f5fa724de

This PR adds new logic to handle the following cases related to `InterruptedException`.
- Check if the message of IOException starts with `java.lang.InterruptedException`. If so, treat it as `InterruptedException`. This is for pre-Hadoop 2.8.
- Treat `InterruptedIOException` as `InterruptedException`. This is for Hadoop 2.8+ and other places that may throw `InterruptedIOException` when the thread is interrupted.

## How was this patch tested?

The new unit test.
