### Description There is a meta-task for adding [Cartesian support for aggregations](https://github.com/elastic/elasticsearch/issues/87804), and this issue is one of the proposed sub-tasks, the distance aggregation. It is modelled on the existing [`geo_distance`](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-geodistance-aggregation.html) and as such could be called either: * `cartesian_distance` * or just `distance` It is expected to be based on the previous work on https://github.com/elastic/elasticsearch/issues/90156 and https://github.com/elastic/elasticsearch/issues/90157
