Automate release with Github actions (#302)

The current process according the README is manual.
It requires to have access users to DockerHub.

After small investigation, found that DockerHub is not actively
internaly used and decided to switch container registry to Github.

The relase part was done with [goreleaser](https://github.com/goreleaser/goreleaser).
It can create Release in Github, Container registries and Homebrew.

Update documentation to use Github container registry for new versions.
