Server::local_addr() cannot be called with executor

[njaard]

Similar to #1638 but I think the problem is about the executor:

let addr: &str = ...;
let exec = tokio::runtime::current_thread::TaskExecutor::current();
let server = hyper::Server::bind(&addr.parse().expect("parsing address"))
  .executor(exec)
  .serve(new_service);
let _ = server.local_addr();

// no method named `local_addr` found for type    `hyper::server::Server<hyper::server::tcp::AddrIncoming, [closure@main.rs:206:5: 216:6 main:_], tokio_current_thread::TaskExecutor>` in the current scope

Simply removing the .executor(exec) line solves the problem

I can't tell why local_addr depends on the executor's type.

Probably the impl<S> Server<AddrStream, S> block needs to add a generic for the executor, like impl<S, E> Server<AddrStream, S, E>...
