Restructure the repo towards xarm-grpc-service

[iomz]

• xarm-grpc-service: repo including xarm-deamon and .proto definitions
• wot-fx/../nodewot-xarm: implements a gRPC client using the xarm-grpc-service as a submodule (to get the .proto definitions?)
• xarm-commander: two options
  • seperate repo using the xarm-grpc-service as a submodule
  • or: included in xarm-grpc-service as tool or example

This, however, should better be outside the scope of this repository.

Yes, that's what I meant. I was not sure if the xarm-commander and the xarm-grpc-service should be in the same repository?
