#730 did heroic work to convert from error-chain to failure, but our initial consumer (a logins API that consumes Mentat and is in turn consumed by applications like Mozilla Lockbox) is finding that returning failure::Error isn't very helpful. It looks like we'll need to adopt the Error/ErrorKind pattern from 868273409c/book/src/error-errorkind.md.
