// Removes the null version (if there is one) of an object and inserts a delete
// marker, which becomes the latest version of the object. If there isn't a null
// version, Amazon S3 does not remove any objects but will still respond that the
// command was successful. To remove a specific version, you must be the bucket
// owner and you must use the version Id subresource. Using this subresource
// permanently deletes the version. If the object deleted is a delete marker,
// Amazon S3 sets the response header, x-amz-delete-marker, to true. If the object
// you want to delete is in a bucket where the bucket versioning configuration is
// MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE
// versionId request. Requests that include x-amz-mfa must use HTTPS. For more
// information about MFA Delete, see Using MFA Delete
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingMFADelete.html). To see
// sample requests that use versioning, see Sample Request
// (https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectDELETE.html#ExampleVersionObjectDelete).
// You can delete objects by explicitly calling DELETE Object or configure its
// lifecycle (PutBucketLifecycle
// (https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketLifecycle.html))
// to enable Amazon S3 to remove them for you. If you want to block users or
// accounts from removing or deleting objects from your bucket, you must deny them
// the s3:DeleteObject, s3:DeleteObjectVersion, and s3:PutLifeCycleConfiguration
// actions. The following action is related to DeleteObject:
