Enable idempontency for UserRefreshOverUserRangeWorker
Related to #341022 (closed).
We added support for deduplication for workers that uses load balancing was added in !69372 (merged), and this support is still under the feature flag (preserve_latest_wal_locations_for_idempotent_jobs
), we need to add a guard that will conditionally check if a worker is idempotent?
depending on the feature flag in case the worker utilizes load balancing capabilities.
This is just a safety measure, that in case we disable the mentioned feature flag, we don't end up reading stale data.
