As of `http-body` 0.4.1 its has had a `BoxBody` type similar to
`tonic::body::BoxBody`. It also has `Empty` and `Body::map_{data,err}`.
That means all the custom body things we had in tonic can basically be
replaced with that.
Note that this is a breaking change so we should merge this next time we
decide to ship a breaking release.
The breaking changes are:
- `tonic::body::Body` has been removed. I think its fine for users to
depend directly on `http-body` if they need this trait.
- `tonic::body::BoxBody` is now just a type alias for
`http_body::combinators::BoxBody<Bytes, Status>`. So the methods it
previously had are gone. The replacements are
- `tonic::body::Body::new` -> `http_body::Body::boxed`
- `tonic::body::Body::map_from` -> `http_body::Body::map_data` and
`http_body::Body::map_err` depending on which part you want to map.
- `tonic::body::Body::empty` -> `http_body::Empty`
Additionally a `Sync` bound has been added to a few methods. I actually
don't think this is a breaking change because the old
`tonic::body::Body` trait had `Sync` as a supertrait meaning the `Sync`
requirement was already there.

Adds `tonic::Extensions` which is a newtype around `http::Extensions`.
Request extensions can be set by interceptors with
`Request::extensions_mut` and retrieved from RPCs with
`Request::extensions`. Extensions can also be set in tower middleware
and will be carried through to the RPC.
Since response extensions cannot be set by interceptors the main use
case is to set them in RPCs and retrieve them in tower middlewares.
Figured that might be useful.

Doing
```rust
let clone = self.inner.clone();
Box::pin(async move {
let response = clone.call(request).await?;
Ok(response)
})
```
If `self.inner` is (or contains) a `tower::buffer::Buffer` might panic.
That is because cloning a `Buffer` drops the permit that was acquired in
`poll_ready`, meaning it is no longer ready and panic in `call`.
The solution is to use `mem::replace` to take the ready service and pass
that into the async block.
