Gets and sets the property SSLSupportMethod. If you specify a value for IAMCertificateId,
            you must also specify how you want CloudFront     to serve HTTPS requests. Valid values
            are vip and sni-only. If you specify vip, CloudFront uses     dedicated IP addresses
            for your content and can respond to HTTPS requests from any viewer.     However, you
            must request permission to use this feature, and you incur additional monthly    
            charges. If you specify sni-only, CloudFront can only respond to HTTPS requests from
                viewers that support Server Name Indication (SNI). All modern browsers support
            SNI,     but some browsers still in use don't support SNI. Do not specify a value
            for SSLSupportMethod if you     specified true for CloudFrontDefaultCertificate.
