The current version of the cc_vyos.py module supports only network config version 1 (in 1.2) or version 2 (in 1.3). We need to add support for both versions to be sure that the system can accept all kinds of configurations.
The configuration module for 1.3 is compatible with both network-config versions now. Initial testing was successful, but let's keep this for some time to collect more cases.
Setting Ethernet interfaces addresses, routes, and name servers are supported in both versions now. Advanced features like bonding, bridges, VLANs could be added later on-demand.
