Via IRC, the discussion mentions that the incoming eni file has ip/cidr vs ip/netmask.

OpenNebula Datasource now has a network_config property which returns netplan (v2) config.

Here's what's happening

     cloudinit.distro.gentoo.apply_network_config() # this fails, not implemented

Thus this converts OpenNebula netplan into internal state, and then into eni, passing that to distros to call net_util.translate_settings.

The issue is that if the eni passed in uses address, then the parser does not provide a 'netmask' key in the returned dictionary which all of the distros using net_util expect.
