feat(service): rename Service to HttpService, re-export tower::Se…

…rvice` The only important trait for a user is the `tower::Service` trait, which is now available also at `hyper::service::Service`. The other "trait aliases" are no longer publicly exported, as people thought they had to implement them. Also removes dependency on `tower-make`, which is trivial but otherwise shouldn't affect anyone. Closes #1959
