GenerateObjectKey

Generate valid S3 object key (see https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html#object-key-guidelines) by calculating the MD5 digest in hex format of the provided filename.

    my $Key = $BackendObject->GenerateObjectKey(
        ArticleID    => 42,
        Filename     => 'nice.jpeg',
        IsAttachment => 1,              # (optional)
    );

The key format matches following pattern \d+/(attachments/)?[a-f0-9]{32}).
