[#444] cmd/node: Serve ReputationService on the node

Register reputation service server that:
  * verifies signatures of the requests and signs the responses;
  * attaches response meta header to the responses;
  * logs body structures of the requests (only as initial implementation, in
    future it will be replaces with local trust storage).
