Add Multi-Architecture Redis Performance Comparison Infrastructure

Overview

This PR introduces a new Terraform deployment configuration for comparing Redis performance across multiple CPU architectures using AWS bare metal instances. The infrastructure enables comprehensive benchmarking of Redis across different processor types.

What's Added

• New Terraform Module: oss-multi-arch-comp-metal-amd-arm-intel-redis-latest/
• Multi-Architecture Support: Infrastructure for deploying Redis on Intel, AMD, and ARM architectures
• Automated Redis Installation: Cloud-init scripts that build Redis from source
• Benchmarking Client: Dedicated client instance with memtier and benchmark tools

Infrastructure Components

• Database Instances: Configurable bare metal instances for each architecture
  • Intel: m7i.metal-24xl
  • AMD: m7a.metal-48xl
  • ARM: m8g.metal-24xl
• Client Instance: c6in.8xlarge for running benchmarks
• Security Groups: SSH-only access with proper network isolation
