> Implement Accumulo-style visibility labels. Consider the following design 
> principles:
> - Coprocessor based implementation
> - Minimal to no changes to core code
> - Use KeyValue tags (HBASE-7448) to carry labels
> - Use OperationWithAttributes# {get,set}Attribute for handling visibility 
> labels in the API
> - Implement a new filter for evaluating visibility labels as KVs are streamed 
> through.
> This approach would be consistent in deployment and API details with other 
> per-KV security work, supporting environments where they might be both be 
> employed, even stacked on some tables.
> See the parent issue for more discussion.
