Integrate Obfuscator for `PinotTaskConfig` related logs

https://github.com/apache/pinot/pull/7407/files added `Obfuscator` but it's not integrated with minion tasks.

```
Finished task: RealtimeToOfflineSegmentsTask with configs: {uploadURL=http://localhost:9000/segments, maxNumRecordsPerSegment=1000000000, authToken=xxx, ...

Starting task: RealtimeToOfflineSegmentsTask with configs: {uploadURL=http://localhost:9000/segments, maxNumRecordsPerSegment=1000000000, authToken=xx, ...

Start running RealtimeToOfflineSegmentsTask: Task_RealtimeToOfflineSegmentsTask_6373b2d2-5cd1-4942-91f6-85e14d0d4380_1685494803973_0 with configs: {uploadURL=http://localhost:9000/segments, maxNumRecordsPerSegment=1000000000, authToken=xx,...
```

Start with the Obfuscator added in pull request 7407 and trace how minion tasks log PinotTaskConfig values, including the Finished task, Starting task, and Start running task messages shown here. Identify the relevant task entry points and verify that sensitive configuration values are obfuscated in each message before considering the work done.
