config: Allow auto-creating new filters based on settings key paths

This is especially needed for old-set-parser where e.g. auth_worker_max_count
converts to service/auth-worker/process_limit. This worked so far because
service/auth was created as a non-default settings filter, so it was simply
updated. However, with the next change service/auth becomes a "service
default" filter, which can't be directly updated. Instead a whole new
non-default service/auth filter must be created.

This change shouldn't break anything, although it will now allow
auto-creating named list filters in configuration file, e.g.
"namespace/inbox/separator=/" will directly work.
