This removes the `tcp` feature from hyper's `Cargo.toml`, and the code it enabled: - `HttpConnector` - `GaiResolver` - `AddrStream` And parts of `Client` and `Server` that used those types. Alternatives will be available in the `hyper-util` crate. Closes #2856 Co-authored-by: MrGunflame <mrgunflame@protonmail.com>
