…stic#39238) `ReadOnlyEngine` never recovers operations from translog and never updates translog information in the index shard's recovery state, even though the recovery state goes through the `TRANSLOG` stage during the recovery. It means that recovery information for frozen shards indicates an unkown number of recovered translog ops in the Recovery APIs (translog_ops: `-1` and translog_ops_percent: `-1.0%`) and this is confusing. This commit changes the `recoverFromTranslog()` method in `ReadOnlyEngine` so that it always recover from an empty translog snapshot, allowing the recovery state translog information to be correctly updated.
