Expose adaptive concurrency limits configuration

[aburan28]

Description:

It would be very useful if I was able to configure adaptive concurrency settings on envoy gateway. Right now I'm using envoypatchpolicy but potentially including this on ClientTrafficPolicy or BackendTrafficPolicy would be great. An example CRD that does similar things can be found here https://docs.solo.io/gloo-mesh-enterprise/main/resiliency/adaptive-request-concurrency/

If agreed that this should be supported I'm happy to take a stab at implementation

wdyt @envoyproxy/gateway-maintainers @envoyproxy/gateway-reviewers, +1 from me

[zirain]

+1 on this

[aburan28]

I'll make a quick proposal for this but I'm thinking that this would make the most sense to add via the ClientTrafficPolicy.

@aburan28 since its tied to upstream it should be in BackendTrafficPolicy where circuitBreakers also reside

+1.
