/// Add middleware to service
///
/// ## Overview
///
/// Middleware decorates a service, adding additional functionality. It is a
/// concept common to most web frameworks.
///
/// Tower Web uses the Tower stack for middleware (hence the name). This example
/// decorates the application with the LogMiddleware. This middleware logs
/// information for each request.
///
/// ## Usage
///
/// Run the example:
///
///     RUST_LOG="hello_world=info" cargo run --example middleware
///
/// Then send a request:
///
///     curl -v http://localhost:8080/
