I think now clustering metrics are not that general, comparing with
classification/regression metrics:
WSSSE only apply to `KMeans` and `BiKMeans`
Loglikelihood only apply to `GMM`
I had opened a jira about clusteringEvaluator
https://issues.apache.org/jira/browse/SPARK-14516, which may add metrics
included in scikit-learn
http://scikit-learn.org/stable/modules/classes.html#module-sklearn.metrics.cluster
@yanboliang @jkbradley What's your opinion?
