TerraForm stack for deploying GenAI examples using Cloud Run on Google Cloud

[arun-gupta]

Create a TerraForm stack that allows to deploy GenAI examples using Cloud Run on Google Cloud. The template should take an argument of which sample to deploy, setup all the necessary Google Cloud resources, and then give a publicly accessible URL where the example can be tested.

The stack should be modular such that other samples can be added later on with minimal effort.

Detailed instructions for each sample from https://github.com/opea-project/GenAIExamples/tree/main?tab=readme-ov-file.

This is a specific issue for Google Cloud for the mega issue at https://github.com/opea-project/GenAIExamples/issues/427.
