DRILL-4142: Implement basic query level memory maximums.
- Add new AllocatorDecorator helper class.
- Update BaseAllocator/BufferAllocator to support unwrap(Class<T>) functionality
- Create a new QueryAllocator that survives as long as at least one fragment allocator exists.
- Expose synchronized QueryAllocator creation per node via the WorkEventBus
- Expose a new SYSTEM-only option: "exec.memory.max.per_query_per_node.mb" with a default of 1TB.
