[SPARK-24454][ML][PYTHON] Imports image module in ml/__init__.py and add
ImageSchema into __all__
## What changes were proposed in this pull request?
This PR attaches image APIs to ml module too to more expose this.
## How was this patch tested?
Before:
```python
>>> from pyspark import ml
>>> ml.image
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'image'
>>> ml.image.ImageSchema
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'image'
```
```python
>>> "ImageSchema" in globals()
False
>>> from pyspark.ml import *
>>> "ImageSchema" in globals()
False
>>> ImageSchema
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'ImageSchema' is not defined
```
After:
```python
>>> from pyspark import ml
>>> ml.image
<module 'pyspark.ml.image' from '/.../spark/python/pyspark/ml/image.pyc'>
>>> ml.image.ImageSchema
<pyspark.ml.image._ImageSchema object at 0x1066adf10>
```
```python
>>> "ImageSchema" in globals()
False
>>> from pyspark.ml import *
>>> "ImageSchema" in globals()
True
>>> ImageSchema
<pyspark.ml.image._ImageSchema object at 0x101e86f10>
```
