[SPARK-6746B] Refactor large functions in DAGScheduler to improve
readibility
Hi all. The DAG Scheduler had several very large, complex, and unreadable
functions. Specifically,
```handleTaskCompletion```, ```cleanupStateForJobAndIndependentStages```,
and ```submitMissingTasks```. This patch is almost exclusively code movement,
very little code has changed with the exception of handling return logic when
serializing tasks within ```submitMissingTasks```.
I believe the final product is much more readable and makes it much easier
to understand what's going on within the DAGScheduler.
