Merge branch 'docker_build' into 'master'

Auto-build and push docker image

On every push to the master branch, if tests pass, build and publish a new version of the Docker image, with `latest` tag. Additionally, build and publish an image with tag, taken from git, if git push defines a new tag.

See merge request postgres-ai/postgres-checkup!303
