[GKE] End to End setup of Multi Region Autopilot Kubernetes Cluster with Application Deployment Example

We are going to deploy an Active-Active Architecture Multi-Region Kubernetes Cluster with Terraform in this story.
This will make our cluster highly available since we have two different clusters to serve the traffic and fault tolerant since we are deploying both clusters in different regions. In the worst case even if one region goes down, we will be able to serve traffic from second region cluster.

In my previous story we configured KEDA on Kubernetes. Today we will configure our Autopilot Kubernetes cluster on Google cloud platform with multi region support, and we will deploy a sample application with ingress to verify that traffic is getting served from both the clusters.
