- Add Kubernetes examples demonstrating deployment of various applications (PostgreSQL, Redis, generic). This improves the documentation and provides practical usage examples. - Add `tokio` dependency for async examples. This enables the use of asynchronous operations in the examples. - Add `once_cell` dependency for improved resource management in Kubernetes module. This allows efficient management of singletons and other resources.
