  === RouteToRequestUrl Filter
  
  The `RouteToRequestUrlFilter` runs if there is a `Route` object in the `ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR` exchange attribute. It creates a new URI, based off of the request URI, but updated with the URI attribute of the `Route` object. The new URI is placed in the `ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR` exchange attribute`.
  
  If the URI has a scheme prefix, such as `lb:ws://serviceid`, the `lb` scheme is stripped from the URI and placed in the `ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR` for use later in the filter chain.
