request help: Using nginx annotations like behaviour for client certificate authentication

[FlR-1231]

Issue description

With ingress-nginx it is possible to control the client certificate authentication for specific ingress controllers. (https://github.com/kubernetes/ingress-nginx/blob/main/docs/user-guide/nginx-configuration/annotations.md#client-certificate-authentication)

For example I want to set the auth-tls-verify-client flag, which maps to ssl_verify_client, for certain ingresses.

Even though I search through the different APISIX-Repos I could not find anything similar to achieve this behavior. Is this by any means possible, or does APISIX has very limited capabilities in regards to this?
