[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.
