More improvements to CircleCI configuration (#2777)

* Moved configuration to `.circleci/config.yml` as the documentation for V2 suggests.
* Created a dedicated Docker Compose configuration (in `.circleci/docker-compose.yml`) to remove volumes configuration as this is not supported with CircleCI's Docker executer.
* Fix the Docker image build and tarball packing jobs to work and use correct version.
