How to install protoc environment for Go

From gRPC quickstart Go article

Install the protoc compiler

# Download the latest version for your architecture. In out case 3.11.4-linux-x86_64
$ curl -LO https://github.com/protocolbuffers/protobuf/releases/download/v3.11.4/protoc-3.11.4-linux-x86_64.zip

# Unzip the file under $HOME/.local or a directory of your choice. For example:
$ unzip protoc-3.11.4-linux-x86_64.zip -d $HOME/.local

# Update your environment’s path variable to include the path to the protoc executable. For example:
$ export PATH="$PATH:$HOME/.local/bin"

Install the protoc plugin for Go (protoc-gen-go)

# Install the plugin
$ go get github.com/golang/protobuf/protoc-gen-go

# Update your PATH so that the protoc compiler can find the plugin:
$ export PATH="$PATH:$(go env GOPATH)/bin"

In this project we are adding the protoc-gen-plugin to the PATH in the Makefile
