Alex Crawford 48df1be793 feat(convertNetconf): Add support for network config conversion
Adding the flag -convertNetconf which is used to specify the config
format to convert from (right now, only 'debian' is supported).
Once the network configs are generated, they are written to
systemd's runtime network directory and the network is restarted.
