Summary of Changes

Hello @qevolg, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements a new feature to automatically report the version of the Python WebSocket connector to the server. This allows for better tracking and identification of client applications connecting to the service. The changes involve embedding the connector's version string into connection DSNs and consumer builders, alongside necessary updates to Rust dependencies and the introduction of dedicated tests to ensure the functionality works as expected.

Highlights

• Connector Version Reporting: The Python WebSocket connector now reports its version information (e.g., 'PythonWS-X.Y.Z') to the server, enhancing client identification.
• Dependency Updates: Several Rust dependencies were updated, including the addition of chrono-tz, phf, signal-hook-registry, siphasher, and tokio-util, while deadpool and deadpool-runtime were removed. The taos-connector-rust dependency was also updated to a specific feature branch.
• New Test Cases: New tests have been added to verify that the connector version information is correctly reported for both standard connections and consumer instances.

Code Review

This pull request successfully adds the functionality to report connector version information. The changes in the Rust code are correct and effectively implement the feature. My review focuses on the new Python tests, where I've suggested improvements to enhance their reliability and readability. Specifically, I've pointed out the use of fixed time.sleep() calls, which can lead to flaky tests, and recommended replacing them with a more robust polling mechanism. I've also provided suggestions to make the test code more concise and Pythonic. Additionally, I've noted a skipped test and asked for clarification on its status.
