/**
* This connection pool factory is only needed for a niche use case, but it
* serves as an example of what is possible when creating a custom
* connectionPoolFactory.
*
* If your dsn provider returns servers as hostnames instead of FQDNs or IPs,
* you may have systems that are unable to resolve the hostnames due to
* misconfigured DNS settings. If you are unable to fix the DNS resolution for
* whatever reason, and you know what the FQDN suffix is, you can use this
* connectionPoolFactory to add the suffix.
* @param {string} suffix - The FQDN suffix to use if your dsn's server is provided
*  as a hostname.
* @return {Promise} A promise that uses a dsn provided by the dsnProvider to create
*  an mssql ConnectionPool.
