In AC and VC we have to add the per cell ACL tags/ visibility tags to Cells. We get KeyValue objects and which need one backing array with key,value and tags. So in order to add a tag we have to recreate buffer the and copy the entire key , value and tags. We can avoid this
Create a new Cell impl which wraps the original Cell and fro the non tag parts just refer this old buffer.
This will contain a byte[] state for the tags part.
Also we have to ensure we deal with Cells n write path not KV.
