module: fortios_system_vdom_property
short_description: Configure VDOM property in Fortinet's FortiOS and FortiGate.
description:
    - This module is able to configure a FortiGate or FortiOS (FOS) device by allowing the
      user to set and modify system feature and vdom_property category.
      Examples include all parameters and values need to be adjusted to datasources before usage.
      Tested with FOS v6.0.0
