[SPARK-2355] Add checker for the number of clusters
When the number of clusters given to perform with
org.apache.spark.mllib.clustering.KMeans under parallel initial mode is greater
than data number, it will throw ArrayIndexOutOfBoundsException.
This PR adds checker for the number of clusters and throws
IllegalArgumentException when that number is greater than data number.
