v7 fails with Microsoft.Orleans.Hosting.Kubernetes

When v7 is used with Microsoft.Orleans.Hosting.Kubernetes 7.0.0 it fails to interact with ClusterVersion CRD (see logs below). The hosting library is using KubernetesClient 7.0.7 while v7 clustering us using 6.0.19. The root cause is that KubernetesClient 7.0.7 library is used at runtime and it changes object returned by ListNamespacedCustomObjectAsync, GetNamespacedCustomObjectAsync, etc. from Newtonsoft.Json.Linq.JObject (assumed in 6.0.19) to System.Text.Json.JsonElement.

Fix here 😃

I can try to fix it by upgrading KubernetesClient to 7.x.y version and switching from NewtonsoftJson to System.Text.Json. The officially supported Kubernetes version would go from 1.22 to 1.23.

Would that be ok with @galvesribeiro ?
