hyukjinkwon 044b33b2ed [SPARK-24740][PYTHON][ML] Make PySpark's tests compatible with NumPy 1.14+
## What changes were proposed in this pull request?

This PR proposes to make PySpark's tests compatible with NumPy 0.14+
NumPy 0.14.x introduced rather radical changes about its string representation.

For example, the tests below are failed:

```
**********************************************************************
File "/.../spark/python/pyspark/ml/linalg/__init__.py", line 895, in __main__.DenseMatrix.__str__
Failed example:
    print(dm)
Expected:
    DenseMatrix([[ 0.,  2.],
                 [ 1.,  3.]])
Got:
    DenseMatrix([[0., 2.],
                 [1., 3.]])
**********************************************************************
File "/.../spark/python/pyspark/ml/linalg/__init__.py", line 899, in __main__.DenseMatrix.__str__
Failed example:
    print(dm)
Expected:
    DenseMatrix([[ 0.,  1.],
                 [ 2.,  3.]])
Got:
    DenseMatrix([[0., 1.],
                 [2., 3.]])
**********************************************************************
File "/.../spark/python/pyspark/ml/linalg/__init__.py", line 939, in __main__.DenseMatrix.toArray
Failed example:
    m.toArray()
Expected:
    array([[ 0.,  2.],
           [ 1.,  3.]])
Got:
    array([[0., 2.],
           [1., 3.]])
**********************************************************************
File "/.../spark/python/pyspark/ml/linalg/__init__.py", line 324, in __main__.DenseVector.dot
Failed example:
    dense.dot(np.reshape([1., 2., 3., 4.], (2, 2), order='F'))
Expected:
    array([  5.,  11.])
Got:
    array([ 5., 11.])
**********************************************************************
File "/.../spark/python/pyspark/ml/linalg/__init__.py", line 567, in __main__.SparseVector.dot
Failed example:
    a.dot(np.array([[1, 1], [2, 2], [3, 3], [4, 4]]))
Expected:
    array([ 22.,  22.])
Got:
    array([22., 22.])
```

Benjamin Peterson 7013eea11c [SPARK-23522][PYTHON] always use sys.exit over builtin exit
The exit() builtin is only for interactive use. applications should use sys.exit().

## What changes were proposed in this pull request?

All usage of the builtin `exit()` function is replaced by `sys.exit()`.

## How was this patch tested?

I ran `python/run-tests`.
