[SPARK-25764][ML][EXAMPLES] Update BisectingKMeans example to use
ClusteringEvaluator
## What changes were proposed in this pull request?
Using `computeCost` for evaluating a model is a very poor approach. We
should advice the users to a better approach which is available, ie. using the
`ClusteringEvaluator` to evaluate their models. The PR updates the examples for
`BisectingKMeans` in order to do that.
## How was this patch tested?
