This pull request makes several improvements and refactorings to the HANA DB high-availability Ansible roles, focusing on more robust and streamlined network partition testing, improved error handling, and minor logic corrections. The most important changes are grouped below:

Network Partition Test Refactoring and Robustness:

• The network partition test (secondary-block-network.yml) is refactored to block all network communication on secondary site nodes using iptables -P DROP, applied in parallel to all secondary nodes, instead of adding/removing individual firewall rules per IP. This simplifies the logic and ensures a more reliable partition. [1] [2]
• The playbook now includes a rescue step that resets iptables policies to ACCEPT on secondary site nodes in case of test failure, ensuring the cluster is not left in a partitioned state.

Logic and Validation Improvements:

• The test validation logic for worker node operations is updated to ensure the target worker node is actually present in the expected site after the operation, improving test accuracy.
• A condition is added to only execute the primary node kill test when the saphanasr_provider is set to SAPHanaSR-angi, preventing unintended execution in other configurations.

Timeout and Error Handling:

• The default timeout value for test waits is increased from 60 to 90 seconds, allowing more time for cluster state changes and reducing spurious test failures in slow environments.
• The use of Jinja templating is removed from changed_when and failed_when expressions for better readability and reliability.

Test Reporting:

• Test case reporting is updated to reflect the new network partitioning approach, indicating that the firewall was blocked on the secondary site and removed by fencing (node reboot), rather than by explicit firewall rule removal.

These changes collectively improve the reliability, maintainability, and clarity of the HANA DB HA test automation.
