The OCV Operator installation via CLI doesn't include the label `openshift.io/cluster-monitoring: "true"` in the `ns/openshift-cnv`. This differs from an installation done via the web console, where the label is created automatically.

4.14+ (also tested on 4.16)

Always

1. Install OCV via cli and check the command below. Nothing is returned
  ```
  $ oc describe ns openshift-cnv| grep monitoring
  ```
2. Install OCV via web console and check the command below. It returns the label openshift.io/cluster-monitoring
  ```
  $ oc describe ns openshift-cnv| grep monitoring
  openshift.io/cluster-monitoring=true 
  ``` 

One installation method has the label openshift.io/cluster-monitoring, the other doesn't.

Both installation methods (cli and web console) should produce the same result.

To do so, we should update our docs and include that `label` in this [namespace section](https://docs.openshift.com/container-platform/4.14/virt/install/installing-virt.html#installing-virt-operator-cli_installing-virt:~:text=apiVersion%3A%20v1-,kind%3A%20Namespace,-metadata%3A%0A%20%20name) as below:

```
apiVersion: v1
kind: Namespace
metadata:
  name: openshift-cnv
  labels:
    openshift.io/cluster-monitoring: "true"
```
