This new controller produces an intermediate output (ComputedRoutes) that is meant to summarize all relevant xRoutes and related mesh configuration in an easier-to-use format for downstream use to construct the ProxyStateTemplate. It also applies status updates to the xRoute resource types to indicate that they are themselves semantically valid inputs.
