* fix client publish panic

If broker connect returns error we dont check it status and use
it later to publish message, mostly this is unexpected because
broker connection failed and we cant use it.
Also proposed solution have benefit - we flag connection status
only when we have succeseful broker connection

GRPC Server

The grpc server is a micro.Server compatible server.

Overview

The server makes use of the google.golang.org/grpc framework for the underlying server but continues to use micro handler signatures and protoc-gen-micro generated code.

Usage

Specify the server to your micro service

import (
        "github.com/micro/go-micro"
        "github.com/micro/go-plugins/server/grpc"
)

func main() {
        service := micro.NewService(
                // This needs to be first as it replaces the underlying server
                // which causes any configuration set before it
                // to be discarded
                micro.Server(grpc.NewServer()),
                micro.Name("greeter"),
        )
}

NOTE: Setting the gRPC server and/or client causes the underlying the server/client to be replaced which causes any previous configuration set on that server/client to be discarded. It is therefore recommended to set gRPC server/client before any other configuration
