If something causes the number k8s resources to increase beyond a
certain threshold, garbage collection can fail because the query to
retrieve those resources will time out, resulting in a perpetual cycle
of being unable to garbage collect resources.
In lieu of trying to get *every* object each cycle, we can limit the
number of resources retrieved per GC cycle to some reasonable number.
