Code Review

This pull request focuses on integrating Titanium dependencies and migrating from Akka to Pekko. The changes involve updating dependency versions in POM files, adjusting configuration files (JSON and Helm templates) to use Pekko paths and class names, and updating YANG module revisions. There are also some related code changes to adapt to API updates in the new dependency versions. Overall, the core changes for the Pekko migration seem mechanically correct based on the diffs provided.

Summary of Findings

• Pekko Management Configuration Duplication: The pekko-default.conf file includes a pekko.management.http configuration block that might be redundant or conflict with management settings provided via Helm chart values in a Kubernetes deployment. (Medium severity, commented)
• Pekko Snapshot Directory: The snapshot-store.local.dir property is commented out in pekko-default.conf, changing the default snapshot location. The intended new location and its suitability for persistence should be clarified. (Medium severity, commented)
• Datastore File Path: A hardcoded path Path.of("data") is now used for the datastore base directory. Clarification on its purpose and consideration for making it configurable for different deployment environments would be beneficial. (Medium severity, commented)
• Snapshot Repository in POMs: The opendaylight-snapshot repository is added to several POM files with a TODO to remove it later. This is acceptable for a WIP branch but should be addressed before merging to a stable branch. (Low severity, not commented)
• API Adaptations: The code correctly adapts to API changes in updated dependencies, including Pekko, AAA, and Netconf databind. (Low severity, not commented)
• Test Code Refactoring: Test code has been refactored to use a library class (CompletingServerRequest) instead of a local definition, which is a good practice. (Low severity, not commented)
• Configuration File Updates: Configuration files (JSON, Helm templates, .conf) have been updated consistently with the Pekko migration and YANG model revisions. (Low severity, not commented)

Merge Readiness

This pull request introduces significant dependency updates and the migration to Pekko. While the core migration changes appear mechanically correct, there are a few medium-severity issues identified related to configuration clarity and potential conflicts (Pekko management config, snapshot directory, datastore path). Given that this is marked as WIP and these points require clarification or potential adjustments for production readiness, I recommend addressing the commented issues before merging. I am unable to approve this pull request; please have other reviewers review and approve this code before merging.
