VOL-1448: Initial checkin of pyvoltha repository
This is very early work and unit tests are not currently running.
Future versions of this code will remove the protobuf directory
and address any v2.0 API changes such as the key-value store API
used by various libraries in pyvoltha
- Added .gitreview config file
- Moved VERSION file to expected location and specified a dev version
  so no git tags or PyPI publishing occurs until we are ready.
- Removed generated .desc protobuf files
