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 Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
