Crash when getting metadata with podman

[abompard]

The format that podman inspect returns does not seem to fit the format that conu expects when getting the metadata. I'm trying to use container.is_port_open() but it fails with a TypeError. Here is a simple script to reproduce it:

import logging
from conu import PodmanBackend

with PodmanBackend(logging_level=logging.DEBUG) as backend:
    image = backend.ImageClass("quay.io/bodhi-ci/postgresql", tag="latest")
    container = image.run_via_binary()
    print(container.get_metadata())

This is the output:
