[SPARK-5484] Checkpoint every 25 iterations in Pregel
Pregel-based iterative algorithms with more than ~50 iterations begin to
slow down and eventually fail with a StackOverflowError due to Spark's lack of
support for long lineage chains.
This PR causes Pregel to checkpoint the graph every 25 iterations if the
checkpoint directory is set.
