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'>
```

## What changes were proposed in this pull request?
Made DataFrame-based API primary
* Spark doc menu bar and other places now link to ml-guide.html, not mllib-guide.html
* mllib-guide.html keeps RDD-specific list of features, with a link at the top redirecting people to ml-guide.html
* ml-guide.html includes a "maintenance mode" announcement about the RDD-based API
* **Reviewers: please check this carefully**
* (minor) Titles for DF API no longer include "- spark.ml" suffix. Titles for RDD API have "- RDD-based API" suffix
* Moved migration guide to ml-guide from mllib-guide
* Also moved past guides from mllib-migration-guides to ml-migration-guides, with a redirect link on mllib-migration-guides
* **Reviewers**: I did not change any of the content of the migration guides.
Reorganized DataFrame-based guide:
* ml-guide.html mimics the old mllib-guide.html page in terms of content: overview, migration guide, etc.
* Moved Pipeline description into ml-pipeline.html and moved tuning into ml-tuning.html
* **Reviewers**: I did not change the content of these guides, except some intro text.
* Sidebar remains the same, but with pipeline and tuning sections added
Other:
* ml-classification-regression.html: Moved text about linear methods to new section in page

Generated docs locally

Closes#14213 from jkbradley/ml-guide-2.0.
## What changes were proposed in this pull request?
Copy the package documentation from Scala/Java to Python for ML package and remove beta tags. Not super sure if we want to keep the BETA tag but since we are making it the default it seems like probably the time to remove it (happy to put it back in if we want to keep it BETA).
## How was this patch tested?
Python documentation built locally as HTML and text and verified output.
