Description

In SPARK-23451 the method computeCost from KMeans was deprecated, as we have now a better way to evaluate a clustering algorithm (the ClusteringEvaluator). Moreover, in the deprecation, the method was targeted for removal in 3.0.

I think we should deprecate the computeCost method on BisectingKMeans for the same reasons.
