Extended support X-Forwarded-* headers

In addition to configuration provided by #220

• internalProxies
• trustedProxies
• ...?

I don't know if it should be part of that issue since Extended support scope is not totally clear for me.

Regarding #249 you made the choice to support some X-Forwarded-* headers even not standard but common like X-Forwarded-Host

I'm aware that Reactor project is not directly linked to Spring but Spring Framework through ForwardedHeaderFilter also take in consideration X-Forwarded-Prefix (that could be truly useful when mapping to different context-path).

So do you think is relevant for reactor-netty to get more consistent with plain old Servlet Spring Framework version?

If an extended support is needed there is a possibility for a custom handler to be provided instead of the default one. See #990
