impl Encodable<tower_hyper::Body> is missing

[dingxiangfei2009]

In case that tower_hyper is enabled on tower-grpc-build crate, the client code is still not usable since impl client::Encodable<tower_hyper::Body> is missing, cf.

tower-grpc/tower-grpc/src/client/mod.rs

Line 159 in 9ee81e8

impl<T, U> Encodable<BoxBody> for T

Currently, the workaround is by wrapping the service from tower_hyper and inside impl Service using BoxBody::map_from for fn call.

The codegen currently does this for the server here https://github.com/tower-rs/tower-grpc/blob/master/tower-grpc-build/src/server.rs#L313

What is your use case for the client side? iirc you shouldn't have to worry about this when generating codegen since the client will just use BoxBody.

Currently I am trying to use tokio::net::UnixStream as the transport. It is first wrapped into a hyper client by impl hyper::client::connect::Connect, and lifted into a tokio_hyper client. Note that a tokio_hyper client always uses hyper::Body instead of the designated body type, according to its impl Service.
