Graceful Shutdown - Clean shutdown with in-flight request handling

Provides graceful shutdown support for cloud deployments:

• Stops accepting new requests
• Waits for in-flight requests to complete
• Has a timeout for forced shutdown

Usage

let shutdown = GracefulShutdown::new(Duration::from_secs(30));
 
// In your request handler
let guard = shutdown.start_request()?;
// ... do work ...
drop(guard); // Request complete

// When shutting down
shutdown.initiate();
shutdown.wait_for_completion().await;
