docs: Start OpenID verification without doing OpenID server
          discovery. This method is used internally by Consumer.begin
          after discovery is performed, and exists to provide an
          interface for library users needing to perform their own
          discovery.
  
          @param service: an OpenID service endpoint descriptor.  This
              object and factories for it are found in the
              L{openid.consumer.discover} module.
  
          @type service:
              L{OpenIDServiceEndpoint<openid.consumer.discover.OpenIDServiceEndpoint>}
  
          @returns: an OpenID authentication request object.
  
          @rtype: L{AuthRequest<openid.consumer.consumer.AuthRequest>}
