This PR contains the work done to support the building of Docker images in the `Build` subcommand in the executable target. So, for this purpose, the following task have been done:
- added a basic boilerplate of the `docker-compose.yml` file;
- fixed some issues found in the boilerplate of the `Dockerfile` file;
- defined the `Randomable` protocol;
- defined the `Artifact` enumeration;
- updated the `BuildProjectTask` task to support building Docker images if required;
- renamed the `BuildProjectTask` task as `BuildArtifactTask`.
