Spent sometime refactoring the .NET variation of GCF with multi-stage builds. It simplified the install/setup instructions considerably. - [https://github.com/salrashid123/cloud-functions-dotnet#quickstart--buildrun-with-cloud-shell](https://github.com/salrashid123/cloud-functions-dotnet#quickstart--buildrun-with-cloud-shell) (basically use multistage builds to compile execer, install the required .NET...

IMO, its fine to close this out w/ a note about debian10 (since its not just an issue with this library; i'd call it not in scope to hunt down...

not sure if this covers the same thing but i put together a trivial standalone xds server that works with grpc clients [here](https://github.com/salrashid123/grpc_xds) using `github.com/envoyproxy/go-control-plane v0.9.4` `google.golang.org/grpc v1.33.2`
