Large-memory improvements (Memory reduced vertex implementation, fast failure, added settings)

-----------------------------------------------------------------------------------------------

                 Key: GIRAPH-91
                 URL: https://issues.apache.org/jira/browse/GIRAPH-91
             Project: Giraph
          Issue Type: Improvement
            Reporter: Avery Ching


Current vertex implementation uses a HashMap for storing the edges, which is quite memory
heavy for large graphs.  The default settings in Giraph need to be improved for large graphs
and heaps of >20G.
