Yuya Nishihara c333481496 cli: add more CommandError factory functions, consolidate inner type
I'm going to reorganize CommandError as (kind, err, hints) tuple so that we
can add_hint() to the constructed error object.

Some config error messages are slightly adjusted because the inner error is
now printed in separate line.
