> * Reduce scope of next_lock_id select-for-update by moving the txn_component
> inserts before the S4U + inserting the hive_locks entries before the S4U
> (first with a temp ID, which will be replaced later in a single update). This
> helps decrease the overall time that the next_lock_id table is locked,
> thereby increasing concurrency
> * Insert txn_components in a batch instead of one-by-one (also in
> TxnHandler::addDynamicPartition)
> * Increment next_lock_id and update hive_locks table in a single batch
> statement
