Description

Several classes and methods have been deprecated and are creating lots of build warnings in branch-2.0. This issue is to identify and fix those items:

• *WithSGD classes: Change to make class not deprecated, object deprecated, and public class constructor deprecated. Any public use will require a deprecated API. We need to keep a non-deprecated private API since we cannot eliminate certain uses: Python API, streaming algs, and examples.
  • Use in PythonMLlibAPI: Change to using private constructors
  • Streaming algs: No warnings after we un-deprecate the classes
  • Examples: Deprecate or change ones which use deprecated APIs
• MulticlassMetrics fields (precision, etc.)
