Merge pull request #467 from squito/executor_job_id

include jobid in Executor commandline args
Update default.parallelism docs, have StandaloneSchedulerBackend use it.

Only brand new RDDs (e.g. parallelize and makeRDD) now use default
parallelism, everything else uses their largest parent's partitioner
or partition size.
Remove fileServerSuite.txt.
Tweak test names.
support customized java options for master, worker, executor, repl shell
Update more javadocs.
Avoid a shuffle if combineByKey is passed the same partitioner.
Add assertion about dependencies.
Merge pull request #469 from stephenh/samepartitionercombine

If combineByKey is using the same partitioner, skip the shuffle.
Make CoGroupedRDDs explicitly have the same key type.
Move ParallelCollection into spark.rdd package.
Add RDD.subtract.

Instead of reusing the cogroup primitive, this adds a SubtractedRDD
that knows it only needs to keep rdd1's values (per split) in memory.
