Publish Docker image

[IlyaSemenov]

Can we have an officially published Docker image, ideally updated and re-tagged with CI/CD?

There's an official Docker image jkuri/bore-server:latest already. I missed mention that in the README.md.

@jkuri do you have the bore-client as Docker image too? I'd like to use inside my docker-compose file
