PR Summary

• Enhancement of Mock Data: We've enhanced our pseudo data commonly used for testing or simulation, by adding a new information field, 'server_count'. This field would initialize with a value of 0 and is available in both JavaScript and Python test objects.
• Improvement on Data Transfer Tool: We've updated our tool used for sending/receiving data (cURL command) to also include 'server_count' information in its data update (PATCH) requests, alongside the previously available 'command_count'. This allows us to monitor and update the count of servers efficiently.
