> Minor code re-organization to do the following:
> # The OpportunisticContainerAllocatorAMService currently allocates outside the ApplicationAttempt
lock maintained by the ApplicationMasterService. This should happen inside the lock.
> # Refactored out some code to simplify the allocate() method.
> # Removed some unused fields inside the OpportunisticContainerAllocator.
> # Re-organized some of the code in the OpportunisticContainerAllocatorAMService::allocate
method to make it a bit more readable.
> # Moved SchedulerRequestKey to a new package, so it can be used by the OpportunisticContainerAllocator/Context.
> # Moved all usages of Priority in the OpportunisticContainerAllocator -> SchedulerRequestKey.
