[SPARK-15784][ML]:Add Power Iteration Clustering to spark.ml
## What changes were proposed in this pull request?
As we discssed in the JIRA, `PowerIterationClustering` is added as a
`Transformer`. The `featureCol` is `vector` type. In the `transform` method, it
calls `MLlibPowerIterationClustering().run(rdd)` method and transforms the
return value `assignments` (the Kmeans output of the pseudo-eigenvector) as a
Dataframe (`id`: `LongType`, `cluster`: `IntegerType`).
## How was this patch tested?
Add new unit tests similar to `MLlibPowerIterationClustering`.
