> In order to help improve usage tracking, allocations for a single query should all roll
up to a single root.
> This requires that the Foreman create that root, and label it, and then pass that along
to anyone else that needs to create additional sub-allocators. The patch for DRILL-2406 introduces
the creation of a new allocator in QueryContext, but this is currently a child of the Drillbit's
TopLevelAllocator, violating the principle above. This is a reminder to fix that after the
dependencies above are available.
