[FLINK-2140][gelly] Allowed access to the number of vertices in the GSA functions
Similar to the vertex-centric approach, this PR enables users to access the total number of vertices from within the gather, sum and/or apply functions of a GSA iteration.

> Similarly to the Vertex-centric approach we would like to allow the user to access the number of vertices from the Gather, Sum and Apply functions respectively. This property will become available by setting [setOptNumVertices()] the numVertices option to true.
> The number of vertices can then be accessed in the gather, sum and apply functions using the getNumberOfVertices() method. If the option is not set in the configuration, this method will return -1.
