https://github.com/apache/spark/pull/18742
Python persistence helper functions
## What changes were proposed in this pull request?
Added DefaultParamsWriteable, DefaultParamsReadable, DefaultParamsWriter,
and DefaultParamsReader to Python to support Python-only persistence of
Json-serializable parameters.
## How was this patch tested?
Instantiated an estimator with Json-serializable parameters (ex.
LogisticRegression), saved it using the added helper functions, and loaded it
back, and compared it to the original instance to make sure it is the same.
This test was done in both the Python REPL and the unit tests.
Note to reviewers: there are a few excess comments that I left in the code
for clarity but will remove before the code is merged to master.

Working default read and write helper functions. Code does not pass style
tests and still has comments.
