Glosary clarification: translator

[Martin Bukatovic]

Tendrl Architectural Guidelines mentions a concept of translator, but the Glossary file doesn't mention it at all.

I would suggest to either include description of translator into Glossary, or provide the comparison between translator and (node) agent in the description of node agent.

Moreover there is a conflict with translator of GlusterFS terminology, so if this terndrl translator is not well established yet, I would suggest to rename it to avoid confusion. That said, it's a general term so maybe I'm wrong and glossary description would be good enough.
