    Inject log-driver for podman containers

    Currently, docker daemon runtime has a default --log-driver set
    to journald.

    Podman lack of daemon prevent such a global application, meaning
    we have to set that driver for each and every container when we
    either create or run them.

    Notes:
    - podman only supports "json-file", and it's not even a json.
    - docker json-file doesn't support "path" option, making this output
      unusable in the end: logs end in
      /var/lib/docker/containers/ID/ID-json.log
