Initial draft PR

We still need to define how to set the CALLBACK_URL

These environment variables are merged to the .env file quoted in the following order:

Terraform passed env vars ( This is not optional nor customizable )
Repository checked-in env vars - repo_env file as default. (KEY=VALUE style)
Github Vars - Create a variable in your GH Repo - (KEY=VALUE style)
Github Secret - Create a secret in your GH Repo - (KEY=VALUE style)
AWS Secret - Comma separated list of JSON style like '{"key":"value"}' secrets.```

    environment:
      name: ${{ github.ref_name }}
      url: ${{ steps.deploy.outputs.vm_url }}

Same comments on env names as in the prod deploy file

 with:
        aws_access_key_id: ${{ secrets.AWS_ACCESS_KEY_ID_JIRA_INTEGRATIONS}}
        aws_secret_access_key: ${{ secrets.AWS_SECRET_ACCESS_KEY_JIRA_INTEGRATIONS}}
        aws_default_region: us-east-1

These should be the (new?) staging env secrets
