Thanks.
Currently I found NaiveBayes and LDA use Matrix in saving/loading. [~mengxr] Shall we add convertMatrixColumnsToML in 2.0?
+PCA+ also uses Matrix.

> To help users migrate from Spark 1.6. to 2.0, we should make model loading backward compatible with models saved in 1.6. The main incompatibility is the vector column type change.
