Remove main execution block from Quasar model and add configuration files for testing

- Eliminated the main execution block from the Quasar model for cleaner code.
- Introduced new configuration files `config_1.conf` and `config_2.conf` for Quasar devices, detailing interface settings and IP configurations.
- Added expected output JSON files `config_1.expected.json` and `config_2.expected.json` to validate the parsing of Quasar configurations against expected results.
