// Returns a list of configuration items for the specified resource. The list

// interval. If you specified a retention period to retain your ConfigurationItems
// between a minimum of 30 days and a maximum of 7 years (2557 days), AWS Config
// returns the ConfigurationItems for the specified retention period.
//
// The response is paginated. By default, AWS Config returns a limit of 10 configuration
// items per page. You can customize this number with the limit parameter. The
// response includes a nextToken string. To get the next page of results, run
// the request again and specify the string for the nextToken parameter.
//
// Each call to the API is limited to span a duration of seven days. It is likely
// that the number of records returned is smaller than the specified limit.
// In such cases, you can make another call, using the nextToken.
