Equivalence cache for CheckNodeConditionPred becomes invalid when Node.Spec.Unschedulable changes. This can happen even if Node.Status.Conditions does not change, so move the logic around. This logic is covered by integration test "test/integration/scheduler".TestUnschedulableNodes but equivalence cache is currently skipped when test pods have no OwnerReference. Add benchmark for equivalence hashing. Change equivalence hash function. This changes the equivalence class hashing function to use as inputs all the Pod fields which are read by FitPredicates. Before we used a combination of OwnerReference and PersistentVolumeClaim info, which was a close approximation. The new method ensures that hashing remains correct regardless of controller behavior. The PVCSet field can be removed from equivalencePod because it is implicitly included in the Volume list. Tests are now broken. Move equivalence class hash code. This moves the equivalence hashing code from algorithm/predicates/utils.go to core/equivalence_cache.go. In the process, making the hashing function and hashing function factory both injectable dependencies is removed. Fix equivalence cache hash tests.
