Description

Is your feature request related to a problem? Please describe. I have a gateway in production behind a reverse, but in dev mode i d'ont have a proxy, i need to disabled for the production the header.

Describe the solution you'd like Add a mode to add the X-Forward-x header if not present instead of disabled or append mode

Contributor guide

Research direction
Examine the existing XForwardedHeadersFilter or similar classes in the spring cloud gateway module. Understand the current 'append' and 'disabled' modes. Implement a new mode that adds X Forwarded * headers only if they are not already present. Follow the existing filter pattern and ensure the change works for both MVC and WebFlux setups.
