    relay: Log if we can't find an address for configured ORPort
    
    Everytime we try to discover an address we want to publish, emit a log notice
    if we are unable to find it even though an ORPort was configured for it.
    
    Because the function can be called quite often, we rate limit that notice to
    every hour so it gets annoying just enough so the operator fixes that.
    
    Related to #40254
