network: T5012: Added a new option for network-config control

A new option for Cloud-Init was added:

```
vyos_config_options:
  network_config: <disabled/enabled>
```

Possible values:

* by default - equal to the `network['config']` from the active Cloud-Init
configuration
* `enabled` - configure networking, even if global `network['config']` is set
to `disabled`
* `disabled` - do not configure networking, regardless of global
`network['config']` value
