* transport: impl Service for Channel instead of GrpcService
This adds tower::Service impl for tonic::transport::Channel
and removes GrpcService impl declaration.
Channel still implements GrpcService, thanks to the general
impl declaration of GrpcService for types who implement Service.
Fixes#481.
* examples: stop using GrpcService to avoid ambiguity
* examples: add timeout example
