feat: Add Kubernetes examples and update dependencies

- 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.

## Features
- **Application Deployment**: Deploy complete applications with a single method call
- **Environment Variables & Labels**: Configure containers with environment variables and Kubernetes labels
- **Resource Lifecycle Management**: Automatic cleanup and replacement of existing resources
- **Namespace-scoped Management**: Each `KubernetesManager` instance operates on a single namespace
- **Pod Management**: List, create, and manage pods
- **Pattern-based Deletion**: Delete resources using PCRE pattern matching
- **Namespace Operations**: Create and manage namespaces (idempotent operations)
- **Resource Management**: Support for pods, services, deployments, configmaps, secrets, and more
- **Rhai Integration**: Full scripting support through Rhai wrappers
- **Rhai Integration**: Full scripting support through Rhai wrappers with environment variables
## Core Concepts
### Labels vs Environment Variables
Understanding the difference between labels and environment variables is crucial for effective Kubernetes deployments:
#### **Labels** (Kubernetes Metadata)
- **Purpose**: Organize, select, and manage Kubernetes resources
- **Scope**: Kubernetes cluster management and resource organization
- **Visibility**: Used by Kubernetes controllers, selectors, and monitoring systems
- **Examples**: `app=my-app`, `tier=backend`, `environment=production`, `version=v1.2.3`
- **Use Cases**: Resource grouping, service discovery, monitoring labels, deployment strategies
#### **Environment Variables** (Container Configuration)
- **Purpose**: Configure application runtime behavior and settings
- **Scope**: Inside container processes - available to your application code
- **Visibility**: Accessible via `process.env`, `os.environ`, etc. in your application
- **Examples**: `NODE_ENV=production`, `DATABASE_URL=postgres://...`, `API_KEY=secret`
- **Use Cases**: Database connections, API keys, feature flags, runtime configuration
#### **Example: Complete Application Configuration**
```rust
// Labels: For Kubernetes resource management
let mut labels = HashMap::new();
labels.insert("app".to_string(), "web-api".to_string()); // Service discovery
labels.insert("tier".to_string(), "backend".to_string()); // Architecture layer
labels.insert("environment".to_string(), "production".to_string()); // Deployment stage
labels.insert("version".to_string(), "v2.1.0".to_string()); // Release version
// Environment Variables: For application configuration
let mut env_vars = HashMap::new();
env_vars.insert("NODE_ENV".to_string(), "production".to_string()); // Runtime mode
env_vars.insert("DATABASE_URL".to_string(), "postgres://db:5432/app".to_string()); // DB connection
env_vars.insert("REDIS_URL".to_string(), "redis://cache:6379".to_string()); // Cache connection
env_vars.insert("LOG_LEVEL".to_string(), "info".to_string()); // Logging config
```
## Usage
### Application Deployment (Recommended)
Deploy complete applications with labels and environment variables:
```rust
use sal_kubernetes::KubernetesManager;
use std::collections::HashMap;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let km = KubernetesManager::new("default").await?;
// Configure labels for Kubernetes resource organization
let mut labels = HashMap::new();
labels.insert("app".to_string(), "my-app".to_string());
labels.insert("tier".to_string(), "backend".to_string());
// Configure environment variables for the container
let mut env_vars = HashMap::new();
env_vars.insert("NODE_ENV".to_string(), "production".to_string());
env_vars.insert("DATABASE_URL".to_string(), "postgres://db:5432/myapp".to_string());
env_vars.insert("API_KEY".to_string(), "secret-api-key".to_string());
// Deploy application with deployment + service
km.deploy_application(
"my-app", // name
"node:18-alpine", // image
3, // replicas
3000, // port
Some(labels), // Kubernetes labels
Some(env_vars), // container environment variables
).await?;
println!("✅ Application deployed successfully!");
Ok(())

## Security Considerations
### Test Requirements
- **Kubernetes Cluster**: Integration tests require a running Kubernetes cluster
- **Environment Variable**: Set `KUBERNETES_TEST_ENABLED=1` to enable integration tests
- **Permissions**: Tests require permissions to create/delete resources in the `default` namespace
## Production Considerations
### Security
- Always use specific PCRE patterns to avoid accidental deletion of important resources
- Test deletion patterns in a safe environment first
- Ensure proper RBAC permissions are configured
- Be cautious with cluster-wide operations like namespace listing
- Consider using dry-run approaches when possible
- Use Kubernetes secrets for sensitive environment variables instead of plain text
### Performance & Scalability
- Consider adding resource limits (CPU/memory) for production deployments
- Use persistent volumes for stateful applications
- Configure readiness and liveness probes for health checks
- Implement proper monitoring and logging labels
### Environment Variables Best Practices
- Use Kubernetes secrets for sensitive data (passwords, API keys)
- Validate environment variable values before deployment
- Use consistent naming conventions (e.g., `DATABASE_URL`, `API_KEY`)
- Document required vs optional environment variables
### Example: Production-Ready Deployment
```rust
// Production labels for monitoring and management
let mut labels = HashMap::new();
labels.insert("app".to_string(), "web-api".to_string());
labels.insert("version".to_string(), "v1.2.3".to_string());
labels.insert("environment".to_string(), "production".to_string());
labels.insert("team".to_string(), "backend".to_string());
// Non-sensitive environment variables
let mut env_vars = HashMap::new();
env_vars.insert("NODE_ENV".to_string(), "production".to_string());
env_vars.insert("LOG_LEVEL".to_string(), "info".to_string());
env_vars.insert("PORT".to_string(), "3000".to_string());
// Note: Use Kubernetes secrets for DATABASE_URL, API_KEY, etc.
