[Refactor] Refactor SearchStats.Stats to use a builder pattern for non-breaking extensibility. 12 months ago

AI Summary: Refactor the OpenSearch `SearchStats.Stats` class to use a builder pattern instead of a constructor with numerous parameters. This improves extensibility by allowing the addition of new statistics without breaking changes. The existing constructor will be deprecated in 3.x and removed in 4.0. This is necessary to maintain backward compatibility while adding new search metrics.

Complexity: 4/5
