      - Merge "Workaround for unsuccessfully parsed duplicate key error"
      - Workaround for unsuccessfully parsed duplicate key error
    
        Since MySQL server 8.0.19, the table name is prepended to the key name
        in duplicate key error messages. For now, oslo_db exception filter
        fails to successfully parse them, leading to some functional test
        failures. Once the issue is resolved, this patch will become unnecessary.
