Fix default TTL for metadata cleaner It seems to have been set to 3500 in a previous commit for debugging, but it should be off by default.

Better error handling in Spark Streaming and more API cleanup Earlier errors in jobs generated by Spark Streaming (or in the generation of jobs) could not be caught from the main driver thread (i.e. the thread that called StreamingContext.start()) as it would be thrown in different threads. With this change, after `ssc.start`, one can call `ssc.awaitTermination()` which will be block until the ssc is closed, or there is an exception. This makes it easier to debug. This change also adds ssc.stop(<stop-spark-context>) where you can stop StreamingContext without stopping the SparkContext. Also fixes the bug that came up with PRs mesos#393 and mesos#381. MetadataCleaner default value has been changed from 3500 to -1 for normal SparkContext and 3600 when creating a StreamingContext. Also, updated StreamingListenerBus with changes similar to SparkListenerBus in mesos#392. And changed a lot of protected[streaming] to private[streaming].

This threadpool seems unused (unless there is some magic I'm missing somewhere). My guess is that its been replaced by the threadpool in Executor.
