// Updates the parameter values for stack instances for the specified accounts,
// within the specified Regions. A stack instance refers to a stack in a specific
// account and Region. You can only update stack instances in Regions and accounts
// where they already exist; to create additional stack instances, use
// CreateStackInstances
// (https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_CreateStackInstances.html).
// During stack set updates, any parameters overridden for a stack instance are not
// updated, but retain their overridden value. You can only update the parameter
// values that are specified in the stack set; to add or delete a parameter itself,
// use UpdateStackSet
// (https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_UpdateStackSet.html)
// to update the stack set template. If you add a parameter to a template, before
// you can override the parameter value specified in the stack set you must first
// use UpdateStackSet
// (https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_UpdateStackSet.html)
// to update all stack instances with the updated template and parameter value
// specified in the stack set. Once a stack instance has been updated with the new
// parameter, you can then override the parameter value using UpdateStackInstances.

	// stack instance update operations:
	//
	// * To override the current value for a
	// parameter, include the parameter and specify its value.
	//
	// * To leave a parameter
	// set to its present value, you can do one of the following:
	//
	// * Do not include the
	// parameter in the list.
	//
	// * Include the parameter and specify UsePreviousValue as
	// true. (You cannot specify both a value and set UsePreviousValue to true.)
	//
	// * To
	// set all overridden parameter back to the values specified in the stack set,
	// specify a parameter list but do not include any parameters.
	//
	// * To leave all
	// parameters set to their present values, do not specify this property at
	// all.
	//
	// During stack set updates, any parameter values overridden for a stack
