> In the current implementation of the {{OpportunisticContainerAllocatorAMService}}, we
synchronously perform the allocation of opportunistic containers. This results in "blocking"
the service at the RM when scheduling the opportunistic containers.
> The {{OpportunisticContainerAllocator}} should instead asynchronously run as a separate
thread.
