    [FLINK-1707][WIP]Add an Affinity Propagation Library Method

    I just finished the initial version of AP implementation and pass some preliminary test.
The input of the program include two files:
    1 similarity graph : each line indicates the similarity between two vertices. if <v1,
v2, simi> exists, the user is obligatory to ensure the existence of   <v2,v1, simi>.
I am considering validating the graph before run the algorithm.
    2 vertex preference: each line indicates the preference of each vertex.
    The outputs format is : <vertexId, exemplarId>,   indicating the id of the vertex
and the id of its exemplar. 
    
    In the value of each vertex, there is a hashmap storing all the similarities, responsibilities,availabilities
to all its neighbor vertex. There are updated in the vertex centric iteration.
    I still do some test and verification? Any advices?

> This issue proposes adding the an implementation of the Affinity Propagation algorithm
as a Gelly library method and a corresponding example.
> The algorithm is described in paper [1] and a description of a vertex-centric implementation
can be found is [2].
