We should avoid hitting the error :
```
uninitialized constant VagrantPlugins::ProviderLibvirt::Action::ShareFolders
```

because of ips addresses conflicts.
This commit ensures each scenario has a uniq subnet for both public and cluster
network so we can setup several test environment at a time on a same hypervisor.
