    [SPARK-24294] Throw SparkException when OOM in BroadcastExchangeExec

    ## What changes were proposed in this pull request?
    
    When OutOfMemoryError thrown from BroadcastExchangeExec, 
scala.concurrent.Future will hit scala bug – 
https://github.com/scala/bug/issues/9554, and hang until future timeout:
    
    We could wrap the OOM inside SparkException to resolve this issue.
    
    ## How was this patch tested?
    
    Manually tested.
