na_ontap_dns cluster vs. vserver usage

[Sneedes]

Summary

Attempting to configure the DNS servers for an ONTAP Cluster via the na_ontap_dns module. The documentation states: With REST, for cluster scoped DNS, omit this option or set it to NULL.

However, it appears that when I omit the parameter, I encounter the following error: Error getting DNS service: could not retrieve UUID of the DNS object

Unsure if this is a documentation error, usage/interpretation issue on my behalf, of the na_ontap_dns module not behaving as desired for REST/Cluster scope.

Playbook

- name: Configure DNS for the cluster
      netapp.ontap.na_ontap_dns:
        state: present
        hostname: "{{ netapp_hostname }}"
        username: "{{ netapp_username }}"
        password: "{{ netapp_password }}"
        domains: "{{ domains }}"
        nameservers: "{{ dns1 }}"
        use_rest: always
        validate_certs: false
        vserver: "{{ cluster_name }}"

### Steps to Reproduce

- name: Configure DNS for the cluster
  netapp.ontap.na_ontap_dns:
    state: present
    hostname: "{{ netapp_hostname }}"
    username: "{{ netapp_username }}"
    password: "{{ netapp_password }}"
    domains: "{{ domains }}"
    nameservers: "{{ dns1 }}"
    use_rest: always
    validate_certs: false

Run while omitting the vserver parameter, and using rest.  

### Expected Results

I expected with REST, for cluster scoped DNS, I wouldn't have to provide the `vserver` parameter.
