fix(restart): quieter mode

If a user is asking for a `--quiet` restart, he still have lots of messages:

```
Restarting astropaperga on commit xxx
Waiting for deployment to start…
Deployment started (deployment_xxx)
Waiting for application logs…
Deployment successful
```

This fix disable "Waiting messages" and keep only those about deployment starting/result
