✨ Modular pipeline

[tbunata]

Implement modular pipeline using the gitlab ci components: https://gitlab.ack.ee/jiri.smolik/gitlab-component-nodejs/
Features

• supports gitlab environments
• connection to DB using services for tests
  Notes
• components are addressed by commit hash, would be nice to use version tags
• deploy command needs to be single line otherwise component will not parse it correctly
• would be nice to move component repo from personal space to BE group
