This adds a new `_ignored` meta field which indexes and stores fields that have been ignored at index time because of the `ignore_malformed` option. It makes malformed documents easier to identify by using `exists` or `term(s)` queries on the `_ignored` field. Closes elastic#29494

Is this comment still true ? Not related to this pr but it seems that this assumption is true only if the routing field is present, if not we will need to visit every field ?

we should probably put _routing first then (in a different pr)

can you add a comment here saying that this field is always the first in the stored field which is why we can early terminate when required fields is empty ?
