What
Added FOR UPDATE in selection and a transaction to lock the row being updated during authentication refresh.
Added table prefix to the qod_type column of the result iterator.
Why
To reduce the likelihood of a deadlock while refreshing authentication.
Adding the table prefix to qod_type to address SQL errors while filtering results. This was also causing scans to go into interrupted state (See GEA-526)
