Adding basic CI workflow

Adding the basics for the CI workflow include:
- Makefile for running the go commands including lint checks with
golangci-lint
- Chain docker build using the Makefile that outputs an image containing
the final executable
- GitHub action workflow to checkout, build, lint, and test the code and
build the final image. Pushing of the image will be done on a separate
workflow and only done on tagging
