Infra cluster controller

Overview

Infra cluster controller is responsible for managing InfrastructureCluster(AWSCluster, etc.) CRs. The infrastructure cluster object will represent the infrastructure of the cloud(AWS,Azure,GCP, etc.) where current cluster is running.

The controller will set the cluster externally managed annotation "cluster.x-k8s.io/managed-by" and Status.Ready to true which indicates that the cluster is managed by the current controller and not managed by the CAPI infrastructure provider.
