[SPARK-11029] [ML] Add computeCost to KMeansModel in spark.ml
jira: https://issues.apache.org/jira/browse/SPARK-11029
We should add a method analogous to
spark.mllib.clustering.KMeansModel.computeCost to
spark.ml.clustering.KMeansModel.
This will be a temp fix until we have proper evaluators defined for
clustering.
