Minor cleanups in cli/command/container
This change does some minor cleanups in the
cli/command/container package;

- sort imports
- replace `fmt.Fprintf()` with `fmt.Fprintln()` if no formatting is used
- replace `fmt.Errorf()` with `errors.New()` if no formatting is used
- remove some redundant `else`'s
