controls::auto close is set to off on contained databases
Overview
AUTO_CLOSE determines if a given database is closed or not after a connection terminates. If enabled, subsequent connections to the given database will require the database to be reopened and relevant procedure caches to be rebuilt.
Because authentication of users for contained databases occurs within the database not at the server\instance level, the database must be opened every time to authenticate a user. The frequent opening/closing of the database consumes additional server resources and may contribute to a denial of service.

Skipping
To deliberately skip this control (e.g. meaning don’t use Puppet to enforce this setting), we provide you with three ways:
1) Add mssql_secured::controls::auto_close_is_set_to_off_on_contained_databases: skip
to your hiera data. This will skip this control for ALL databases.
2) Add mssql_secured::controls::auto_close_is_set_to_off_on_contained_databases::dbname: skip
to your hiera data. This will skip this control for specified database only.
3) Add an entry with the content auto_close_is_set_to_off_on_contained_databases
to the array value mssql_secured::skip_list
in your hiera data.
