App Log file names with variables configured is not detected!

Hi Team,

I was trying App log Auto-discovery mode, appLog file names with variables configured is not detected.

I passed the app log path in yaml file as follows:

```
appLogs:
- /opt/log/sw1/log$currentdate.txt
```

And then I ran the below debug command.
./yc -c config.yaml -p 25108 -j /usr/java/latest -onlyCapture -logLevel debug
