DescendentFetcher which partitions into model names passed, skips PairTree nodes, and stops after first level of non-PairTree nodes

# Finds all descendent URIs of a given repo URI (usually the base URI).

# This is a slow and non-performant thing to do, we need to fetch every single
# object from the repo.

# The DescendantFetcher is also capable of partitioning the URIs into "priority" URIs
# that will be first in the returned list. These prioritized URIs belong to objects
# with certain hasModel models. This feature is used in some hydra apps that need to
