This avoid the intermediate allocation for every invocation of exert_logic to create a boxed iterator. Instead, pass a slice that contains the same information previously revealed by the iterator. At the same time, wrap the logic in an option to only invoke it if it is set. Signed-off-by: Moritz Hoffmann <[email protected]>

This is the source of around 80% of all allocations in mostly idle Materialize clusters. The lower two large blocks are related to this in the following image.
