Show target cluster in the list of apps.

[wolfedale]

Describe the problem/challenge you have The list of apps are not showing any info about target clusters.

Describe the solution you'd like I would like to execute kubect get Apps and get output something like:

➜  kubectl get Apps
NAME           DESCRIPTION           SINCE-DEPLOY   AGE    CLUSTER
nginx-app      Reconcile succeeded   22s            48m    myClusterFoo   
simple-app     Reconcile succeeded   31s            72m    local
new-app        Reconcile succeeded   21s            32m    local

where local means my management cluster, the one on which I'm executing kubectl or kapp. And myClusterFoo is a string from: app.spec.cluster.kubeconfigSecretRef, with CAPI it's one of my workload cluster.

Example of my App:

apiVersion: kappctrl.k14s.io/v1alpha1
kind: App
metadata:
  name: nginx-app
  namespace: default
spec:
  cluster:
    kubeconfigSecretRef:
      name: myClusterFoo-cluster-kubeconfig
    namespace: default

  fetch:
    - http:
        url: https://raw.githubusercontent.com/kubernetes/website/main/content/en/examples/application/deployment.yaml
  template:
  - ytt: {}
  deploy:
  - kapp: {}

Anything else you would like to add: I'm happy to prepare PR for it :-)

This is awesome, we use similar capabilities and never thought about making this more readable -- we just follow a naming convention on the apps that includes the cluster names (${CLUSTER_NAME}-nginx or similar), this would make this cleaner and more clear for newer folks though.
