…detection-engine-rule-status documents (elastic#112257) **Ticket:** elastic#109815 ## Summary **Background:** `siem-detection-engine-rule-status` documents stores the `lastFailureMessage` a string which is indexed as `type: "text"` but some failure messages are so large that these documents are up to 26MB. These large documents cause migrations to fail because a batch of 1000 documents easily exceed Elasticsearch's `http.max_content_length` which defaults to 100mb. This PR truncates `lastFailureMessage` and `lastSuccessMessage` in the following cases: 1. When we write new or update existing status SOs: - The lists of errors/warnings are deduped -> truncated to max `20` items -> joined to a string - The resulting strings are truncated to max `10240` characters 2. When we migrate `siem-detection-engine-rule-status` SOs to 7.15.2: - The two message fields are truncated to max `10240` characters ### Checklist Delete any items that are not applicable to this PR. - [ ] [Unit or functional tests](https://www.elastic.co/guide/en/kibana/master/development-tests.html) were updated or added to match the most common scenarios
