Non-running containers now report statistics via the `podman stats`

command

Previously, if a container was not running, and the user ran the `podman
stats` command, an error would be reported: `Error: container state
improper`.

Podman now reports stats as the fields' default values for their
respective type if the container is not running:

```
$ podman stats --no-stream demo

ID            NAME        CPU %       MEM USAGE / LIMIT  MEM %       NET IO      BLOCK IO    PIDS        CPU TIME    AVG CPU %
4b4bf8ce84ed  demo        0.00%       0B / 0B            0.00%       0B / 0B     0B / 0B     0           0s          0.00%
```

Closes: #14498
