This commit adds support for specifying a properties file, for use with configuration parameters.

- Added a new field configurationParametersResources of type List<String> to store the configuration parameters resources.
- Added new methods configurationParametersResource(String propertiesFile) and configurationParametersResources(List<String> propertiesFiles) to add configuration parameters resources to the request builder.
- Updated the buildLauncherConfigurationParameters() method to include the configurationParametersResources in the Builder instance.
