// This looks at URLs in syntax of MeasurementProxyUrlNamer, and produces
// a configuration appropriate for them, including whether:
// 1) The URL should be served at all (password, syntax correctness)
// 2) There should be any rewriting happening, given site and resource
//    domains.
// 3) The rewriting should be blocking.
