Instead of patching in the machine config, provide a new interface in
the platforms to supply platform-specific network configuration.
Configuration will be cached in the `/state` across reboots, and
configuration might be even updated in real time (e.g. on GCP).
Network configuration on platform level can be overridden with
user-supplied machine configuration.
