hyukjinkwon 173fe450df [SPARK-24477][SPARK-24454][ML][PYTHON] Imports submodule in ml/__init__.py and add ImageSchema into __all__
## What changes were proposed in this pull request?

This PR attaches submodules to ml's `__init__.py` module.

Also, adds `ImageSchema` into `image.py` explicitly.

## 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
>>> "image" in globals()
False
>>> from pyspark.ml import *
>>> "image" in globals()
False
>>> image
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'image' 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 0x10d973b10>
```

```python
>>> "image" in globals()
False
>>> from pyspark.ml import *
>>> "image" in globals()
True
>>> image
<module 'pyspark.ml.image' from  #'/.../spark/python/pyspark/ml/image.pyc'>
```
