Restructure ProtoBuf & gRPC project structure

- pom.xml {protobuf, grpc}-dependencies to consolidte
  plugin configuration, dependency version property

- {protobuf, grpc}: ONOS App to load required feature/bundle

- all other atrifacts: Apps using protobuf/grpc inherit
  ~-dependencies above to reduce copy & paste configurations and
  dependency versions.
