Support for http2 listener

[prajithp13]

FEATURE REQUEST

Currently, there is no service annotation available to enable the HTTP/2 listener. By default, it creates HTTP and HTTPS listeners for ports 80 and 443, respectively. This limitation makes it challenging to enable the HTTP/2 protocol for OCI load balancer, compelling the use of HTTP(s) when created from Kubernetes.

[AkarshES]

We do not have a plan to support http/2 with Kubernetes services as Kubernetes services are meant to be layer 4 networking abstractions. You can consider using OCI Native Ingress Controller instead though https://github.com/oracle/oci-native-ingress-controller. Let us know if you have a use case which can't be solved by Ingress controller
