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

Browse Source 
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
