CombineParentHealth takes a ParentHealth directly queried from the parent service (ATS or the Origin) and the ParentServiceHealth directly queried from the parent's HealthService, combines them, and returns a ParentServiceHealth with each direct parent's RecursiveParentHealth containing both the direct ParentHealth and the ParentServiceHealth.

DeserializeParentHealth deserializes the ParentHealth from network or disk output, as previously serialized with Serialize.

DeserializeParentServiceHealth deserializes the ParentHealth from network or disk output, as previously serialized with Serialize.
