Improve PseudoRandomVertexInputFormat to create a more realistic synthetic graph (e.g. power-law
distributed vertex-cardinality).

                 Key: GIRAPH-26
                 URL: https://issues.apache.org/jira/browse/GIRAPH-26
             Project: Giraph
          Issue Type: Test
          Components: benchmark
            Reporter: Jake Mannix
            Priority: Minor


The PageRankBenchmark class, to be a proper benchmark, should run over graphs which look more
like data seen in the wild, and web link graphs, social network graphs, and text corpora (represented
as a bipartite graph) all have power-law distributions, so benchmarking a synthetic graph
which looks more like this would be a nice test which would stress cases of uneven split-distribution
and bottlenecks of subclusters of the graph of heavily connected vertices.
