podman-generate-systemd --new
Add a --new flag to podman-generate-systemd to create a new container via podman-run instead of starting an existing container. Creating a new container presents the challenge to find a reverse mapping from a container to the CLI flags it can be created with. We are doing this via `(Container).Config.CreateCommand` field, which includes a copy of the process' command from procFS at creating time. This field may not be useful when the container was not created via the Podman CLI (e.g., via a Python script). Hence, we do not guarantee the correctness of the generated files.
