trigger clean dir when unzip fails with IOException

[kaijianding]

SegmentManager, SegmentLoaderLocalCacheManager, and many pullers catch IOException and wrap IOException as SegmentLoadingException, and only clean dir when SegmentLoadingException happens.
But the unzip method will wrap all exceptions to RuntimeException, then the clean logic is not going to be triggered. unzip should try best to throw IOException instead of RuntimeException

 try {
    return RetryUtils.retry(
        () -> unzip(byteSource.openStream(), outDir),
        shouldRetry,
        DEFAULT_RETRY_COUNT
    );
  }
  catch (Exception e) {
    throw Throwables.propagate(e);// here, RuntimeException is not appropriate
  }
