Description

ML model summary classes (e.g., LinearRegressionSummary) currently expose a field "model" containing the parent model. It's weird to have this circular reference, and I don't see a good reason why the summary should expose it (unless I'm forgetting some decision we made before...).

I'd propose to deprecate that field in 2.0 and to remove it in 2.1.
