docs: Find a connection that matches this kojiweb URL.
  
          Check all koji.conf.d files' kojiweb URLs and load the profile that
          matches the url we pass in here.
  
          For example, if a user pastes a kojiweb URL into chat, we want to
          discover the corresponding Koji instance hub automatically.
