Changes and versioning

Version policy - all the versions we run in production is taged.

In case change will require simultanious upgrade of different components, it will be stated in Upgrading notes below.

Also we will try to maintain backward compatibility from down to up.

For example with protobuf2 -> protobuf3 migration - carbonzipper can still send results to older versions of carbonapi, but can't get results from older versions of carbonserver/go-carbon.

See CHANGES.md
