module: fortios_system_dns
short_description: Configure DNS 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 dns category.
      Examples include all parameters and values need to be adjusted to datasources before usage.
