Implement Kubectl Get using generic client for any Kubernetes resource

[Copilot]

Adds kubectl get functionality to retrieve any Kubernetes resource by name, similar to the kubectl CLI tool. Uses a single generic method with GenericClient instead of separate methods for each resource type.

Implementation

• AsyncKubectl.Get.cs: Generic async GetAsync<T>() method using GenericClient
• Kubectl.Get.cs: Synchronous generic Get<T>() wrapper following existing patterns (Version, Cordon)
• KubectlTests.Get.cs: E2E tests using MinikubeFact for Pod, Service, Deployment, and Namespace

The implementation extracts resource metadata (group, version, plural name) from the type's KubernetesEntityAttribute and automatically handles both namespaced and cluster-scoped resources.

Usage

using k8s.kubectl.beta;

var kubectl = new Kubectl(kubernetesClient);

// Get namespaced resources
var pod = kubectl.Get<V1Pod>("my-pod", "default");
var deployment = kubectl.Get<V1Deployment>("my-deployment", "prod");
var service = kubectl.Get<V1Service>("my-svc", "default");

// Get cluster-scoped resources (no namespace parameter)
var namespace = kubectl.Get<V1Namespace>("kube-system");
var node = kubectl.Get<V1Node>("node-1");

// Async with cancellation
var configMap = await kubectl.GetAsync<V1ConfigMap>("my-config", "default", cancellationToken);

The generic method works with any Kubernetes resource type that has a KubernetesEntityAttribute, making it extensible to all supported resources without requiring additional code.

@copilot can you refactor this to use the generic client

csharp/examples/generic/Generic.cs

Line 7 in 9566a3f

var generic = new GenericClient(client, "", "v1", "nodes");

instead so that it can work for any supported resource type with a single function instead of having different GetFoo functions for each time

Refactored to use GenericClient with a single generic Get<T>() method. The implementation extracts resource metadata from the type's KubernetesEntityAttribute and automatically handles both namespaced and cluster-scoped resources.

Usage:

var pod = kubectl.Get<V1Pod>("my-pod", "default");
var namespace = kubectl.Get<V1Namespace>("kube-system");
var deployment = kubectl.Get<V1Deployment>("my-deploy", "prod");
