(Background, I'm starting what is likely to be an onerous task of 
looking through downstream components and seeing what is broken with the 
latest hbase-2.0.0*)

for downstream users to, ya know, use those Tags. Any objections?

If we don't want to expose Tag, we should make a pass over the Public 
methods and mark them as Private (so not as to provide a Public method 
with Private objects). CellUtil#getTag(Cell, byte) would be one such
