shutdown

Shuts down the cluster and its associated components.

This method closes all active services, stops the HTTP server, and closes the underlying client, ensuring a clean and orderly shutdown of the cluster. The shutdown process is encapsulated within a coroutine to handle suspending operations and is wrapped in a try-catch block to log any errors that occur.

Key operations performed during shutdown:

• Gracefully closes the self session, representing the local node.

• Iterates through and closes all registered services.

• Stops the HTTP server, providing a specific timeout for graceful termination.

• Closes the associated client to free up resources.

Logs any exceptions encountered during the shutdown process as warnings, providing details for troubleshooting.
