Issue: Should not allow to create repair/backup tasks with same name
**Describe the bug**
Currently we allow to have multiple tasks with same name, which should not be the case:

```
    repairs:
    - interval: "0"
      name: test-name
      numRetries: 3
      smallTableThreshold: 1GiB
      startDate: now
    - interval: "0"
      name: test-name
      numRetries: 3
      smallTableThreshold: 1GiB
      startDate: now
```

Fixes #293
