[bug]: KubernetesClient.GetAsync() needs list permission instead of get

[PSanetra]

Describe the bug

Using KubernetesClient.GetAsync() requires the calling client having list permissions on the target resource type.

To reproduce

1. Create a KubernetesClient instance with a service account that has execlusively get permission on pod resources
2. Execute KubernetesClient.GetAsync()
3. The following exception occurs:

k8s.Autorest.HttpOperationException: Operation returned an invalid status code 'Forbidden', response body {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"pods \"my-pod\" is forbidden: User \"system:serviceaccount:my-namespace:my-service-account\" cannot list resource \"pods\" in API group \"\" in the namespace \"my-namespace\"","reason":"Forbidden","details":{"name":"my-pod","kind":"pods"},"code":403}

Expected behavior

KubernetesClient.GetAsync() should work if the client has get permissions on the target resource type.
