* client: always parse the json error message field and return its contents * Use ErrBadRequest and ErrNotFound in every handler and command * Gateway: by default pass underlying service error (configstore, runservice) to client keeping the status code and message. In future, if some errors must be masked, we should change the specific parts that need special handling.
