> spark.ml.LDAModel exposes dependencies on spark.mllib in 2 methods, but it should not:
> * {{def oldLocalModel: OldLocalLDAModel}}
> * {{def getModel: OldLDAModel}}
> This task is to deprecate those methods.  I recommend creating {{private[ml]}} versions of the methods which are used internally in order to avoid deprecation warnings.
> Setting target for 2.2, but I'm OK with getting it into 2.1 if we have time.
