> The DefaultExecutionSlotAllocator should allocate slot in bulks, that means the bulks of slot requests will be sent together and fail if any of the request fails.
> Note this is a first step to fully functional bulk slot allocation. Current limitations would be:
> 1. Slot sharing will be ignored
> 2. Co-location constraints are not allowed
> 3. intra-bulk input location preferences will be ignored
