-----------------------------------

Yeah I have a PR brewing that will fix some of them, like the ones introduced by deprecating
precison/recall in MulticlassMetrics (all should use accuracy)

> 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
> * others (to be listed)
