Control: 6.3.4 Ensure 'user options' database flag for Cloud SQL SQL Server instance is not configured

Description

It is recommended that, user options database flag for Cloud SQL SQL Server instance should not be configured.

The user options option specifies global defaults for all users. A list of default query processing options is established for the duration of a user's work session. The user options option allows you to change the default values of the SET options (if the server's default settings are not appropriate).
