Using C++ as a language for Microservices

Here I try out Functions Framework for C++ on Google Cloud Run.

Motivation:
Provide small footprints (e.g. ~MB) and efficient execution (compared to scripting languages).

Result:
This can be used as an optimization strategy for enhancing performance once a prototype is in place.
