Reuse the the toDelete and toInsert slices within the TreeScheduler to reduce the allocation churn when creating iterators for the B-Tree ascension.

This is an intermediate step to relieve some of the memory usage. We will be going farther than this in how we handle this iterator in the upcoming TreeScheduler refactor.
