Docker 1.9+ networking model support

[quantverse]

Hello,

I would like to ask if there is already any support for the new docker networking model released with version 1.9 (in case containers are launched as services when declared in cloud config)?

Docker-compose supports this with the --x-networking flag.

I see that I am already able to assign network to the container (net: xxx), but I am not able to create a custom network (in cloud config). With docker I would just use docker network create xxx. This should be supported in cloud config, like this (for example):

docker-networks:
  - xxx
  - yyy

This should be supported once libcompose supports Docker Compose v2 format docker/libcompose#147

Is there something going on regarding this?
The docker networking has been here for a while now and seems supported by libcompose as well.
Yet networks keys (as in docker-compose V2/V3 format) specified in RancherOS cloud-config seem to do nothing.
I have to create networks and connect containers to them by hand/separate scripts, which is PITA.

I'm going to add this as a "MAYBE" for v1.2 - I don't currently have time, but we need to have a reminder.
