Controller doesn't show and error when CollectTimeout is over

When collecting a trace, if the `CollecTimeout` delay is reached the perfcollect process is killed, and the trace can't be downloaded. This should be displayed in the controller's log, like in the Error string, such that users can then update the value

```
  --[JOB].collectTimeout                                        Maximum duration of the collect phase. Defaults to 00:05:00 (5 minutes).
```
