   @zhli1142015 current `monotonically_increasing_id` implement causes 
inconsistent behavior vs vinalla spark.
   
   looks in velox we always use one function instance when query has duplicate 
same function expr call

   simple reproduce:
   ```
   val df = sc.parallelize(Seq[Int](), 2).mapPartitions { _ => 
Iterator(Tuple1(1), Tuple1(2)) }.toDF("a")
   val df2 = df.select(monotonically_increasing_id(), 
expr("monotonically_increasing_id()"))
   ```
