should we remove lock.mode from conf

should we remove lock.mode from conf

I'll use “lock.mode” in some other cases.

I think should delete the lock node, which is strongly associated with the store. As for the table name, we should use our default table name just like undolog, and do not need to allow user settings.

I will store the row locks in the user's database, beside the undo_log table, and need a lock node to configure this switcher.
