Summary
-------
Executing clustering using ClusterClassificationDriver in CanopyDriver.
This replaces the existing funtionality. If this refactoring is marked ok, then we can add a threshold as the method parameter/CLI argument to support oulier removal in CanopyClustering.
This patch is first of its kind for the ClusteringDrivers. If this is okayed, then the similar refactoring can be done easily for KMeans, FuzzyK and Dirichlet.
This addresses bug MAHOUT-982.
