replicating nginx.ingress.kubernetes.io/proxy-buffer-size annotation

[novjev]

Hi.

We are looking into migrating from Nginx ingress controller to Envoy Gateway. We customize proxy buffer size to use with an authentication provider.
Is there a way how to customize the equivalent of "nginx.ingress.kubernetes.io/proxy-buffer-size" in Envoy Gateway?

this is being tracked with #3706
