> This is a refactoring task.
> After SPARK-10956 gets merged, we will have the following:
> - MemoryManager
> - StaticMemoryManager
> - ExecutorMemoryManager
> - TaskMemoryManager
> - ShuffleMemoryManager
> This is pretty confusing. The goal is to merge ShuffleMemoryManager and 
> ExecutorMemoryManager and move them into the top-level MemoryManager abstract 
> class. Then TaskMemoryManager should be renamed something else and used by 
> MemoryManager, such that the new hierarchy becomes:
> - MemoryManager
> - StaticMemoryManager
