Natalie Villasana 1a06c2b0c7 adding grpc interface to network state (#33)
* 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
