Add a new tab to utilise egctl x status

*Description*:

We have lots of doc described like:

```plaintext
Verify the HTTPRoute configuration and status:

kubectl get httproute/foo -o yaml
kubectl get httproute/bar -o yaml

Verify the BackendTrafficPolicy configuration:

kubectl get backendtrafficpolicy/fault-injection-50-percent-abort -o yaml
kubectl get backendtrafficpolicy/fault-injection-delay -o yaml

```

It would be nice if we can add a new tab to utilise the ability provided by `egctl x status`.
