[PATCH v2 10/10] terraform: enable Lambda Labs cloud provider in menus

[Luis Chamberlain <mcgrof@kernel.org>]

Enable Lambda Labs as a selectable cloud provider and add example
configurations to help users get started quickly. Lambda Labs is now
fully integrated and available for use.

This patch:
- Adds Lambda Labs to the cloud provider selection menu
- Sources Lambda Labs Kconfig when selected
- Provides example defconfigs for common GPU configurations
- Includes smart selection and cost-optimized examples
- Adds shared SSH key configuration example

Example configurations provided:
- lambdalabs: Basic Lambda Labs setup
- lambdalabs-gpu-1x-a10: Single A10 GPU instance
- lambdalabs-gpu-1x-a100: Single A100 GPU instance
- lambdalabs-gpu-1x-h100: Single H100 GPU instance
- lambdalabs-gpu-8x-a100: 8x A100 GPU cluster
- lambdalabs-gpu-8x-h100: 8x H100 GPU cluster
- lambdalabs-smart: Smart instance selection
- lambdalabs-shared-key: Shared SSH key setup

Lambda Labs is now ready for GPU-accelerated workloads with dynamic
configuration based on real-time API data.
