juju destroy model doesn't delete clusterrole in microk8s

[Andy Wu]

juju add-model will create a clusterrole : <modelname>-modeloperator in microk8s, however , when the model is destroyed, the clusterrole associated with the model is not deleted in microk8s

Steps to reproduce:

1. creat a new juju model
ubuntu@microk8s:~$ juju add-model test-model
Added 'test-model' model on microk8s/localhost with credential 'microk8s' for user 'admin'

2. check clusterrole
ubuntu@microk8s:~$ kubectl get clusterroles | grep test-model
test-model-modeloperator 2021-10-21T19:50:37Z

3. delete the juju model
ubuntu@microk8s:~$ juju destroy-model test-model
WARNING! This command will destroy the "test-model" model.
This includes all containers, applications, data and other resources.

Continue [y/N]? y

4. the previous clusterrole still remain
ubuntu@microk8s:~$ kubectl get clusterroles | grep test-model
