Expose Additional HttpConnectionManager Settings

[Sodman]

kgateway version

v2.0.0

Is your feature request related to a problem? Please describe.

We are missing some toggles and config options which were present in v1.x API, which ultimately configure the Envoy HTTPConnectionManager.

These are the fields we're currently missing:

• useRemoteAddress
• xffNumTrustedHops
• serverHeaderTransformation
• streamIdleTimeout

Envoy ref: https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/network/http_connection_manager/v3/http_connection_manager.proto

Describe the solution you'd like

These can all be implemented in the existing HttpListenerPolicy, as new fields.

Describe alternatives you've considered

Hello @Sodman . I'd like to work on this issue if it's open !!

[Sodman]

Hey @Sweetdevil144, that would be great, thank you! Let us know if you need any more information!

Hi @Sweetdevil144 were you still interested on working on this one?

Looks like some previous work was done in another PR (#11274) that was then dropped

[Sweetdevil144]

#11274 was expected to fix this. Nevertheless I'll start working on this again

Hey @Sweetdevil144 I opened #11462 to implement this feature as we had some more folks asking for it. If you're still interested in contributing to the project please don't hesitate to reach out and we can find an issue for you to work on!
