…le_snapshot` (elastic#137111) In elastic#133954, we modified the `searchable_snapshot` ILM action to clone the index with 0 replicas before performing the force-merge. We didn't take the `index.auto_expand_replicas` setting into account, which could result in the clone having indices after all. That's harmless, as it merely nullifies the optimization of that PR, but we should remove the setting to ensure we achieve the intended optimizations.
