##### SUMMARY
<!--- Describe the new feature/improvement briefly below -->
I would like to be able to set the keyboard layout for graphical console through ansible, as it's already possible via API and UI

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html/rest_api_guide/types#types-display
==> keyboard_layout

##### 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
<!--- Describe how the feature would be used, why it is needed and what it would solve -->
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
    keyboard_layout: de_DE          
```

    storage_domain:
        description:
            - Name of the storage domain where all template disks should be created.
            - This parameter is considered only when C(template) is provided.
            - IMPORTANT - This parameter is not idempotent, if the VM exists and you specify different storage domain,
              disk won't move.
        version_added: "2.4"
    disk_format:
        description:
            - Specify format of the disk.
            - If C(cow) format is used, disk will by created as sparse, so space will be allocated for the volume as needed, also known as I(thin provision).
            - If C(raw) format is used, disk storage will be allocated right away, also known as I(preallocated).
            - Note that this option isn't idempotent as it's not currently possible to change format of the disk via API.
            - This parameter is considered only when C(template) and C(storage domain) is provided.
        choices: [ cow, raw ]
        default: cow

    memory:
        description:
            - Amount of memory of the Virtual Machine. Prefix uses IEC 60027-2 standard (for example 1GiB, 1024MiB).
            - Default value is set by engine.
    memory_guaranteed:
        description:
            - Amount of minimal guaranteed memory of the Virtual Machine.
              Prefix uses IEC 60027-2 standard (for example 1GiB, 1024MiB).
            - C(memory_guaranteed) parameter can't be lower than C(memory) parameter.
            - Default value is set by engine.
