Gets and sets the property TrustedSigners. A complex type that specifies the AWS accounts,
            if any, that you want    to allow to create signed URLs for private content.    If
            you want to require signed URLs in requests for objects in the target    origin that
            match the PathPattern for this cache behavior, specify true    for Enabled, and specify
            the applicable values for Quantity and Items.    For more information, go to Using
            a Signed URL to Serve Private Content    in the Amazon CloudFront Developer Guide.
               If you don't want to require signed URLs in requests for objects that match   
            PathPattern, specify false for Enabled and 0 for Quantity. Omit    Items.    To add,
            change, or remove one or more trusted signers, change Enabled    to true (if it's
            currently false), change Quantity as applicable, and    specify all of the trusted
            signers that you want to include in the updated    distribution.
