feat: execute test with docker compose (#101)

When we changed the application to be executed as distributed nodes (PR #96), performing tests with `docker-compose` became impossible.

To fix this situation in this PR, two new targets are added to `Makefile`:

* `compose_test`
* `compose_test_shell`

These new targets allow one to execute tests and enter the container shell responsible for running these tests.
