How to configure load balancing of HTTP2?

### Some details

I tried to find in documentation how should we configure the Round-robin Load balancing of HTTP2. We are using IHttpForwarder but each time the connection is established all the requests are going to the one instance of the service which has multiple instances.

Since we use Kubernetes, we noticed that on the GRPC client for .NET there is the possibility to set a DNS-based Round-Robin load balancer based on Kubernetes Headless service.

Can I somehow configure this using YARP, I tried searching the documentation but I didn't find anything about it?
