> Say you have a DataFrame with a label column of Integer type.  You can fit a 
> LogisticRegresionModel since LR handles casting to DoubleType internally.
> However, if you call evaluate() on it, then this line does not handle casting 
> properly, so you get a runtime error (MatchError) for an invalid schema: 
> [https://github.com/apache/spark/blob/2cd327ef5e4c3f6b8468ebb2352479a1686b7888/mllib/src/main/scala/org/apache/spark/ml/classification/LogisticRegression.scala#L863]
> We should handle casting.  And test evaluate() with other numeric types.
> **ALSO** We should check elsewhere in logreg and other algorithms to see if 
> we can catch the same issue elsewhere.
