This feature is designed to monitor the lifecycle of mempool objects as they move between the application and the PMD.
It will allow us to track the operations and transitions of each mempool object throughout the system, helping in debugging and understanding objects flow. The implementation include several key components: 1. Added a bitmap to mempool's header (rte_mempool_objhdr) that represent the operations history. 2. Added functions that allow marking operations on an mempool objects. 3. Dumps the history to a file or the console (rte_mempool_objects_dump). 4. Added python script that can parse, analyze the data and present it in an human readable format. 5. Added compilation flag to enable the feature.
