##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
ovirt_vm

##### ADDITIONAL INFORMATION

In countries like Germany, I would like to setup the keyboard layout native to german. This is possible by API and UI, but not using ansible.

<!--- Paste example playbooks or commands between quotes below -->
```yaml
ovirt_vm:
  graphical_console:
    protocol:
      - vnc

```
