    [SPARK-18069][PYTHON] Make PySpark doctests for SQL self-contained

    ## What changes were proposed in this pull request?
    
    This PR proposes to make the examples in Python API documentation as 
self-contained.
    
    These seem pretty common in Python API documentation, for example, 
[pandas](http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.pivot.html#pandas.DataFrame.pivot)
 and [numpy](https://docs.scipy.org/doc/numpy/reference/arrays.ndarray.html).

    ## How was this patch tested?
    
    Manually tested the doctests.
    
    ```
     ./run-tests.py --python-executables=python2.6 --modules=pyspark-sql
     ./run-tests.py --python-executables=python3.6 --modules=pyspark-sql
    ```
    
    Closes #15053
