    [SPARK-23034][Hive][UI] Display tablename for `HiveTableScan` node in UI

    ## What changes were proposed in this pull request?
    
    For queries which scan multiple tables, it will be convenient if the DAG 
shown in Spark UI also showed which table is being scanned. This will make 
debugging easier. For this JIRA, I am scoping those for hive table scans only.
    
    ## How was this patch tested?
