### Summary

Since dnf is not installing the packages when running `dnf download --downloadonly...`, it does not require root access to pull down the rpms. It would be nice if ansible followed the same pattern.

### Issue Type

Feature Idea

### Component Name

dnf

### Additional Information

<!--- Paste example playbooks or commands between quotes below -->
```yaml (paste below)
    - name: Download RPM's
      dnf:
        name: "{{ item }}"
        state: present
        download_only: yes
        download_dir: "{{ rpms_path }}"
      loop: "{{ rpms }}"
```
