.DESCRIPTION
Exports advanced sp_configure global configuration options to sql file.
 
.PARAMETER SqlCredential
Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use:
 
$scred = Get-Credential, this pass $scred object to the param.
 
Windows Authentication will be used if DestinationSqlCredential is not specified. To connect as a different Windows user, run PowerShell as that user.
 
.PARAMETER SqlServer
The SQL Server that you're connecting to.
 
.PARAMETER Path
The Path to the SQL File
 
.PARAMETER WhatIf
