Debug remote chaincode-as-a-service using a reverse proxy to localhost

Identify and document a technique for running chaincode on a remote "cloud," but connected to a process running in a local debugger.

The general idea here is to run a reverse proxy to tunnel gRPC traffic "from" a peer "to" a chaincode endpoint running locally in a debugger. When the peer connects to chaincode, the connection will be relayed back to a port opened on the user's local workstation.


It is worth testing this pattern directly with [ngrok.com](https://ngrok.com) as well as looking into deploying a proxy, router, and ingress/port-forward.
