* examples: update to `tracing` 0.1.14, use `#[instrument]`
Now that `tracing-attributes`'s `#[instrument]` macro plays nicely with
`async-trait`, we can update the tracing example to use `instrument`.
This lets us simplify the events emitted in the example.

* Propagate errors in tls_config instead of unwrap
Ran into `tls_connector` failing and causing our app to panic and shutdown as it seems there wasn't any way to avoid panicking in `tls_config`.
So after talking to @LucioFranco briefly `tls_config` now returns a `Result` instead and propagates errors to the caller, where they can be handled.
* Fix compile warning when tls feature is disabled
This change reverts #366. The `proto/` directory, as described in the guide,
is created under the root of the crate. Not under `src/`.
I've also included a fix to the `grpcurl` endpoint.
Fixed wrong path "proto/helloworld.proto" for `compile_protos` first argument. `build.rs` being in the project root, means the correct path should be "src/proto/helloworld.proto".
* Create an example of an autoreloading server
* Document the autoreloading server example
* Format autoreloading server example
* Add note about cargo-watch in the examples readme
When calling methods on Arc<MyService> where the method is also defined on Arc (e.g. drop and clone), calling inner.#method_ident(request) will actually attempt to call the Arc method instead of the method on the service, resulting in a compile error. This change removes the ambiguity by dereferencing the inner Arc.
This commit adds a new crate `tonic-health` which implements the
[standard GRPC Health Checking][checking] protocol.
Currently there is only a server implementation, though others have
alluded in the discussion in #135 that client implementations exist
which could also be imported as necessary.
A example server has also been added - once the client work is done a
client for this should be added also.
