This commit removes unneeded OpenVPN related code and improves error handling in the alert system. All OpenVPN related functions and html files have been removed. Also, changes are made in the alerting module to raise exceptions instead of returning error messages, which provides a more pythonic way of error handling.
The code changes focus on enhancing the server application's functionality by improving the error handling mechanism and streamlining the logic. Modifications include refining how servers get created, updated, and deleted, optimizing how ssh related actions are performed, and ensuring more accurate server scanning. The changes help reduce potential errors and make the application more efficient.
