Update Test Environment to macOS-14 and Enhance Logging During Test Execution

[marevol]

We've made significant updates to improve our CI/CD pipeline and test logging. Here's a summary of the changes:

1. Execution Environment Update: We've updated the .github/workflows/maven.yml file to switch our CI execution environment from ubuntu-latest to macos-14. This change ensures that our builds and tests have access to the necessary resources for efficient execution.
2. Enhanced Test Logging: To improve the visibility and troubleshooting capabilities of our testing process, we've introduced detailed logging in our test suite. Changes include logging at the beginning and end of test cases in CrudTestBase.java and GsaConfigParserTest.java, providing clear markers for test start and completion points. This aims to simplify identifying issues and understanding test flow.
3. Log Configuration: A new log4j2.xml configuration file has been added to src/test/resources, setting up a standard logging format and level (INFO) across the test suite. This ensures that all test logs follow a consistent format, making them easier to read and analyze.

These changes are designed to enhance our development process by providing a more robust and transparent testing environment.
