[SPARK-5832][Mllib] Add Affinity Propagation clustering algorithm
Affinity Propagation (AP), a graph clustering algorithm based on the
concept of "message passing" between data points. Unlike clustering algorithms
such as k-means or k-medoids, AP does not require the number of clusters to be
determined or estimated before running it. AP is developed by Frey and Dueck.
Please refer to the
[paper](http://www.psi.toronto.edu/affinitypropagation/FreyDueckScience07.pdf).
