[FLINK-2131][ml]: Initialization schemes for k-means clustering
This adds two most common initialization strategies for the k-means
clustering algorithm, namely, Random initialization and kmeans++ initialization.
Further details are at https://issues.apache.org/jira/browse/FLINK-2131
[Edit]: Work on kmeans|| has been started and just needs to be finalized.
[Edit]: kmeans|| implementation finished.
