* Add prefix to `origin` when configuration variables come from ini files Fixes ansible#82387 This change was suggested by @bcoca in https://github.com/ansible/ansible/pull/82388#discussion_r1424235728 and https://github.com/ansible/ansible/pull/82388#discussion_r1424249732 When configuration variables come from an ini file, their `origin` is now set to `ini: <file>`. Similarly, once supported, YAML configuration files will have their `origin` as `yaml: <file>`. Consequently, since unquoting configuration strings should happen if and only if they come from an ini file, this condition boils down to testing whether their `origin` starts with `ini:`. * Do not add prefix to `origin` but explicitly pass `origin_ftype` So as not to rely on a specific format of the `origin` string, as suggested by @sivel in https://github.com/ansible/ansible/pull/82388#issuecomment-1881714871
