[SPARK-5450][GraphX] Add APIs to save a graph as a SequenceFile and load it
As the size of input data increases, building Graph eat much processing
time via
GraphLoader.edgeListFile() or RDD transformations.
APIs to save Graph as a object file is useful for those cases.
The operations are currently slow because of the default
serializer (Java serialization), so efficient serialization
is of future work.
