catch command-not-found errors
Add a special handler to catch errors caused by specifying unknown
commands to Podman. This allows printing a more helpful error message.
```
$ podman
Command "123123" not found.
See `podman --help`.
$ podman pod 123123
Command "123123" not found.
See `podman pod --help`.
```
