// Gets the S3 Intelligent-Tiering configuration from the specified bucket. The S3
// Intelligent-Tiering storage class is designed to optimize storage costs by
// automatically moving data to the most cost-effective storage access tier,
// without performance impact or operational overhead. S3 Intelligent-Tiering
// delivers automatic cost savings in three low latency and high throughput access
// tiers. To get the lowest storage cost on data that can be accessed in minutes to
// hours, you can choose to activate additional archiving capabilities. The S3
// Intelligent-Tiering storage class is the ideal storage class for data with
// unknown, changing, or unpredictable access patterns, independent of object size
// or retention period. If the size of an object is less than 128 KB, it is not
// monitored and not eligible for auto-tiering. Smaller objects can be stored, but
// they are always charged at the Frequent Access tier rates in the S3
// Intelligent-Tiering storage class. For more information, see Storage class for
// automatically optimizing frequently and infrequently accessed objects (https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html#sc-dynamic-data-access)
