Summary: - Add a new option `CompactionOptionsFIFO::file_temperature_age_thresholds` that allows user to specify age thresholds for compacting files to different temperatures. File temperature can be used to store files in different storage media. The new options allows specifying multiple temperature-age pairs. The option uses struct for a temperature-age pair to use the existing parsing functionality to make the option dynamically settable. - Deprecate the old option `age_for_warm` that was added for a similar purpose. - Compaction score calculation logic is updated to check if a file needs to be compacted to change its temperature. - Some refactoring is done in `FIFOCompactionPicker::PickTemperatureChangeCompaction`. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11428 Test Plan: adapted unit tests that were for `age_for_warm` to this new option.
