##### SUMMARY

Add field to ovirt_host_network to configure "Custom Properties" (from oVirt) 

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME

ovirt_host_network

##### 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"
```
