Summary:

The code changes in this pull request primarily focus on removing support for the Couchbase persistence option from the jans-pycloudlib library. This includes the removal of Couchbase-related functionality, configuration options, and test cases. The changes suggest that the library is moving towards a simpler, SQL-based persistence model, with a hybrid mode that allows using SQL for certain data types.

From an application security perspective, the removal of the Couchbase persistence option is generally a positive change, as it reduces the overall complexity and attack surface of the library. Simplifying the persistence layer and focusing on a more standardized SQL-based approach can help improve the security and maintainability of the application.

However, it's important to ensure that the remaining persistence functionality, including the hybrid mode, is properly tested and configured to prevent any potential security vulnerabilities. The changes also highlight the need to review the handling of sensitive data, such as passwords and salts, to ensure they are properly secured and not exposed in the codebase or test suites.

Files Changed:
