Hyper 1 upgrade (#749)
* chore: update hyper/http * chore: update hyper with legacy * Create new workspace dependencies. This makes tracking versions across packages easier. Signed-off-by: David Calavera <david.calavera@gmail.com> * Bring helpers to work with Hyper 1. Copy some of the utils that Axum created to support Hyper 1. Signed-off-by: David Calavera <david.calavera@gmail.com> * Upgrade lambda_runtime to Hyper 1. Signed-off-by: David Calavera <david.calavera@gmail.com> * Upgrade lambda_http to Hyper 1. Signed-off-by: David Calavera <david.calavera@gmail.com> * Update Axum examples to version 0.7. Signed-off-by: David Calavera <david.calavera@gmail.com> * Make extensions compile. Switch to use hyper::service::service_fn definitions. Implement new Hyper's polling loop for http connections. Signed-off-by: David Calavera <david.calavera@gmail.com> * Update tower-http to make cors example work. Signed-off-by: David Calavera <david.calavera@gmail.com> * Update tower-http to make tower-trace example work. Signed-off-by: David Calavera <david.calavera@gmail.com> * Make less copies of extension services. Signed-off-by: David Calavera <david.calavera@gmail.com> * Bring Body::channel implementation from Hyper Given the lack of a public implementation anymore, we don't have other choice but copying Hyper's private implementation. Signed-off-by: David Calavera <david.calavera@gmail.com> * Organize more dependencies. Signed-off-by: David Calavera <david.calavera@gmail.com> * Cleanup commented code. Signed-off-by: David Calavera <david.calavera@gmail.com> * Cleanup unused dependencies. Signed-off-by: David Calavera <david.calavera@gmail.com> * Introduce a module to group all streaming functionality. This makes the streaming functionallity more concise. It aliases other functionality to keep backwards compatibility. Signed-off-by: David Calavera <david.calavera@gmail.com> * Remove unnecesary loop. Signed-off-by: David Calavera <david.calavera@gmail.com> * Don't re-export `lambda_runtime_api_client::body`.
