> Evaluator: support isLargerBetter on connect ML

>          Components: Connect, ML, PySpark
>    Affects Versions: 4.0.0, 4.1.0
>            Reporter: Bobby Wang

> Currently, on connect ML, users couldn't access isLargerBetter from 
> Evaluator, since isLargerBetter is using py4j way to access the corresponding 
> method on scala side. But for current ml connect design, we don't support 
> that.
> To fix this issue, there could be two solutions,
>  # rewrite isLargerBetter in pyspark client side to follow the same 
> implementation as the scala side.
>  # resolve it with a new proto.
