[WIP] [SPARK-4587] [mllib] ML model import/export
This is a WIP PR for Parquet-based model import/export. Please see the
design doc on [the JIRA](https://issues.apache.org/jira/browse/SPARK-4587).
Sketch of current contents:
* New traits: Exportable, Importable with abstract methods save(sc, path)
and load(sc, path), respectively
* Implemented Exportable, Importable for LogisticRegressionModel and added
unit test
* Also: Added LogisticRegressionModel.getThreshold method (so that unit
test could check the threshold)
I will remove the WIP tag after I add save/load for other models in the
spark.mllib package.
