this in before the next RC.
> [0.98] NoTagsKeyValue optimization is not proper

> When the file format is V2, it has no support for tags and so cells will be
> with 0 tags length. For such cells we make NoTagsKeyValue which avoid
> getTagsLength parsing overhead in KeyValue. Still HFileReaderV2 creates
> KeyValue.
> This is a 0.98 issue only.
> Also in case of DBE, we can consider the tags length and return
> KeyValue/NoTagsKeyValue
