##### ADDITIONAL INFORMATION
<!--- Describe how the feature would be used, why it is needed and what it would solve -->
This feature will be used to configure specific options during host's network setup (e.g. custom proprieties for FCoE)

```yaml
- ovirt_host_network:
    name: myhost
    interface: eth0-fcoe
    networks:
      - name: myvlan1
      - name: myvlan2
    custom_proprieties:
      - type: fcoe
        options: "enable=yes,dcb=no,auto_vlan=yes"
```
- "C(name) - Name of the logical network to be assigned to bond or interface."
            - "C(boot_protocol) - Boot protocol one of the I(none), I(static) or I(dhcp)."
            - "C(address) - IP address in case of I(static) boot protocol is used."
            - "C(netmask) - Subnet mask in case of I(static) boot protocol is used."
            - "C(gateway) - Gateway in case of I(static) boot protocol is used."
            - "C(version) - IP version. Either v4 or v6. Default is v4."
    labels:
        description:
            - "List of names of the network label to be assigned to bond or interface."
    check:
        description:
            - "If I(true) verify connectivity between host and engine."
            - "Network configuration changes will be rolled back if connectivity between
               engine and the host is lost after changing network configuration."
        type: bool
    save:
        description:
            - "If I(true) network configuration will be persistent, otherwise it is temporary. Default I(true) since Ansible 2.8."
        type: bool
        default: True
    sync_networks:
        description:
            - "If I(true) all networks will be synchronized before modification"
        type: bool
        default: false
