TASK DESCRIPTION - ItemTermStore should be used to **lookup** terms of Items (starting from item id) that are below the upper-bound configured in T224542 <https://phabricator.wikimedia.org/T224542>, once items migration is switched to `read one` mode. All other terms for items that are above the upper-bound should continue to read from `wb_terms` (using `TermsSqlIndex` class). - For search (starting with text to get term ids), logic will have to read from both schemas and combine the results into one result set. - Careful here. Final result set need to be filtered for distinct results as the old `wb_terms` might still contain terms of all items below the upper-bound (which are now migrated to new schema). Migrated item terms will not be deleted directly after migration, and might never happen until we drop `wb_terms` at once a bit further in the future.
