Caddy is capable of handling bidirectional gRPC streams! I have just tested it, and it works just fine. Caddy will immediately flush writes when upstream is `h2` or `h2c`[0] instead of having to wait until reading from socket is complete

I used this Caddyfile to proxy to the route_guide example (https://github.com/grpc/grpc-go/tree/master/examples/route_g...):

```

localhost {

    reverse_proxy  h2c://localhost:50051

}

```

It works like a charm.
