Yanbo Liang b656e6134f [SPARK-10026] [ML] [PySpark] Implement some common Params for regression in PySpark
LinearRegression and LogisticRegression lack of some Params for Python, and some Params are not shared classes which lead we need to write them for each class. These kinds of Params are list here:
```scala
HasElasticNetParam
HasFitIntercept
HasStandardization
HasThresholds
```
Here we implement them in shared params at Python side and make LinearRegression/LogisticRegression parameters peer with Scala one.

Closes #8508 from yanboliang/spark-10026.

```StringIndexerModel``` lacks of method ```labels```.
```VectorIndexerModel``` lacks of methods ```numFeatures``` and ```categoryMaps```.

MechCoder 20bb10f864 [SPARK-8706] [PYSPARK] [PROJECT INFRA] Add pylint checks to PySpark
This adds Pylint checks to PySpark.

For now this lazy installs using easy_install to /dev/pylint (similar to the pep8 script).
We still need to figure out what rules to be allowed.

Xiangrui Meng 9c7e802a5a [SPARK-7380] [MLLIB] pipeline stages should be copyable in Python
This PR makes pipeline stages in Python copyable and hence simplifies some implementations. It also includes the following changes:

1. Rename `paramMap` and `defaultParamMap` to `_paramMap` and `_defaultParamMap`, respectively.
2. Accept a list of param maps in `fit`.
3. Use parent uid and name to identify param.
