feat(pageserver): persist aux file policy in index part (#7668)
Part of #7462 ## Summary of changes Tenant config is not persisted unless it's attached on the storage controller. In this pull request, we persist the aux file policy flag in the `index_part.json`. Admins can set `switch_aux_file_policy` in the storage controller or using the page server API. Upon the first aux file gets written, the write path will compare the aux file policy target with the current policy. If it is switch-able, we will do the switch. Otherwise, the original policy will be used. The test cases show what the admins can do / cannot do. The `last_aux_file_policy` is stored in `IndexPart`. Updates to the persisted policy are done via `schedule_index_upload_for_aux_file_policy_update`. On the write path, the writer will update the field. --------- Signed-off-by: Alex Chi Z <chi@neon.tech> Co-authored-by: Joonas Koivunen <joonas@neon.tech>
