Initial Contribution of the rollout-management feature

- Repository functionality for rollout, rolloutgroup entities
- Rollout scheduler to watch and handle running rollouts and start next
group of rollout
- Vaadin view to administrate rollouts and reflect the current rollout
status
- REST resources to cover rollout creation, updating, starting, pausing
and resuming
