Integration: Cluster Registration Terraform Provider for GitOps Integration

## What would you like to be added?
Develop a Terraform provider for cluster registration to enable seamless GitOps integration. This provider will facilitate automated cluster creation, deletion, and management through Infrastructure as Code (IaC) and GitOps workflows.

Requirements Source: #783

## Why is this needed?
Currently, there is no efficient way to manage cluster registration and lifecycle operations through GitOps and Terraform. This feature will provide several benefits:

1. **Enhanced Automation**: Enable fully automated cluster management using Terraform.
2. **GitOps Compatibility**: Align with GitOps practices for declarative infrastructure management.
3. **Scalability**: Support bulk cluster operations and consistent management across environments.
4. **Ease of Use**: Provide a simple and reliable way to integrate cluster registration into existing IaC pipelines.

This feature will streamline cluster management processes and improve operational efficiency.
