feat(volo-http): support extract in timeout handler

[yukiiiteru]

Motivation

The previous TimeoutLayer in volo-http only supports Fn(&HttpContext) -> IntoResponse and defining such a function is not graceful.

This PR adds a new handler trait HandlerWithoutRequest. Like Handler of Route, it supports any arguments supported by FromContext, e.g.,

use volo_http::{Server, StatusCode, Uri, Address, layer::TimeoutLayer, Address, };

async fn hello() -> &'static str {
    "hello, world\n"
}

fn timeout_handler(uri: Uri, peer: Address) -> StatusCode {
    tracing::info!("Timeout on `{}`, peer: {}", uri, peer);
    StatusCode::INTERNAL_SERVER_ERROR
}

#[volo::main]
async fn main() {
    let app = Router::new()
        .route("/", get(hello))
        .layer(TimeoutLayer::new(Duration::from_secs(1), timeout_handler}));

    let addr: SocketAddr = "[::]:8000".parse().unwrap();
    let addr = volo::net::Address::from(addr);

    Server::new(app).run(addr).await.unwrap();
}

Additionally, volo-http re-exports some common types from bytes, http or hyper, while examples avoids direct dependencies on them.
