Once of the last places we see OOM conditions is in aggregations, when combinatorial explosion results in too many buckets being assigned.

We need a way to catch these conditions and abort the request rather than running into OOM.

We're not capturing OOM exceptions with a filters aggregations, would this count as a combinatorial aggregation that this issue would fix?
