podman: APIv2: missing NetworkSettings and failure to start a container

/kind bug

Iteration 2 of my APIv2 & docker-py compatibility tests (see #5553 for the first one).

1. I still had to patch the expected minimal version (from 1.9.0 to 1.8.0).

However, problems (2) and (3) from #5553 are fixed!

2. Attempt to run a container failed due to Salt code that expects NetworkSettings -> Networks to be a non-empty dictionary

Network settings:

Docker 
sudo docker network ls

The data structures look quite different.

Below is the difference between API responses from Docker (19.03.8) and Podman (note the <-- comments):

I did a little bit more digging, and while Salt can’t pass an empty NetworkMode (because of the default fallback value in docker-py), it can provide an explicit network_mode keyword:

sudo salt-call docker.run_container registry.fedoraproject.org/f29/httpd name=httpd bg=true replace=true network_mode=podman port_bindings=8080:8080/tcp

This avoids the 500 error when starting the container:
