* adds proto files for netstate crud * moves netstate grpc client lib into pkg/netstate where grpc netstate service is defined * starts adding grpc client and server tests * moves creation of grpc server into cmd/netstate/main.go, removes pkg/netstate/service.go, adds more client testing * changed all 'Path' and 'Value' fields from strings to bytes, updated tests * changes Get and Delete in proto file to receive 'requests' instead of 'file paths', adds tests for Get, List, and Delete * changes netstate-routes to get 'fileValue' bytes not 'fileInfo' * adds example rpc client in 'examples' and adds more specific debug logs * adds readmes for netstate rpc services and updates netstate-routes
