[SPARK-12368] [ML] [DOC] Better doc for the binary classification
evaluator' metricName
For the BinaryClassificationEvaluator, the scaladoc doesn't mention that
"areaUnderPR" is supported, only that the default is "areadUnderROC".
Also, in the documentation, it is said that:
"The default metric used to choose the best ParamMap can be overriden by
the setMetric method in each of these evaluators."
However, the method is called setMetricName.
This PR aims to fix both issues.
