• darwin/arm64 updates to mean macOS with Apple Silicon CPU

Task:

• Replace the following code segment:

with:

 build: 
   cmds: 
     - GOOS=darwin GOARCH=arm64 go build -o awsrouters-m1 *.go 
  buildMacIntel: 
   cmds: 
     - GOOS=darwin GOARCH=amd64 go build -o awsrouters-intel *.go
 buildWindows: 
   cmds: 
     - GOOS=windows GOARCH=amd64 go build -o awsrouters.exe *.go 
 buildLinux: 
   cmds: 
     - GOOS=linux GOARCH=amd64 go build -o awsrouters-linux

Acceptance criterial:

Allow build for the follow 4 OS/Arch convention:

Create a github action for ci/cd

• Currently, the repo has some information to work on gitlab.
• Update the readme.
• Add a release option.

The Application should be the struct to inject dependency.
Although should be more fields, we should have a field to hold the credentials for AWS. It should be an interface.
