How to expose cluster address resolution for backend-to-backend calls?

YARP is designed around the reverse proxy pipeline, but I have a use case where I need to call downstream services directly from the backend.

Im working in a microservice orchestrator (BFF-style) architecture, where the backend aggregates JSON data (e.g., config, menus) from multiple services.

Ideally, Id like to reuse YARP’s cluster configuration and load balancing logic to resolve a destination and call it via `HttpClient`, something like:

```csharp
var url = await yarpResolver.GetDestinationAsync(clusterId);
var result = await httpClient.GetAsync(url);
```

### Question

Is there a way to resolve a cluster destination (including load balancing/health checks) outside the proxy pipeline?

If not, would it make sense to expose something like:

```csharp
public interface IClusterAddressResolver
{
ValueTask GetDestinationAsync(string clusterId, CancellationToken cancellationToken = default);
}
```
