示例1: DeleteS3BucketWithObjectsInternal
/// <summary>
/// Deletes an S3 bucket which contains objects.
/// An S3 bucket which contains objects cannot be deleted until all the objects
/// in it are deleted. The function deletes all the objects in the specified
/// bucket and then deletes the bucket itself.
/// </summary>
/// <param name="bucketName">The bucket to be deleted.</param>
/// <param name="s3Client">The Amazon S3 Client to use for S3 specific operations.</param>
/// <param name="deleteOptions">Options to control the behavior of the delete operation.</param>
/// <param name="updateCallback">The callback which is used to send updates about the delete operation.</param>
/// <param name="asyncCancelableResult">An IAsyncCancelableResult that can be used to poll or wait for results, or both;
/// this value is also needed when invoking EndDeleteS3BucketWithObjects. IAsyncCancelableResult can also
/// be used to cancel the operation while it's in progress.</param>
