Modify the implementation of MemTracker: 1. Simplify a lot of useless logic; 2. Added MemTrackerTaskPool, as the ancestor of all query and import trackers, This is used to track the local memory usage of all tasks executing; 3. Add cosume/release cache, trigger a cosume/release when the memory accumulation exceeds the parameter mem_tracker_consume_min_size_bytes; 4. Add a new memory leak detection mode (Experimental feature), throw an exception when the remaining statistical value is greater than the specified range when the MemTracker is destructed, and print the accurate statistical value in HTTP, the parameter memory_leak_detection 5. Added Virtual MemTracker, cosume/release will not sync to parent. It will be used when introducing TCMalloc Hook to record memory later, to record the specified memory independently; 6. Modify the GC logic, register the buffer cached in DiskIoMgr as a GC function, and add other GC functions later; 7. Change the global root node from Root MemTracker to Process MemTracker, and remove Process MemTracker in exec_env; 8. Modify the macro that detects whether the memory has reached the upper limit, modify the parameters and default behavior of creating MemTracker, modify the error message format in mem_limit_exceeded, extend and apply transfer_to, remove Metric in MemTracker, etc.; Modify where MemTracker is used: 1. MemPool adds a constructor to create a temporary tracker to avoid a lot of redundant code; 2. Added trackers for global objects such as ChunkAllocator and StorageEngine; 3. Added more fine-grained trackers such as ExprContext; 4. RuntimeState removes FragmentMemTracker, that is, PlanFragmentExecutor mem_tracker, which was previously used for independent statistical scan process memory, and replaces it with _scanner_mem_tracker in OlapScanNode; 5. MemTracker is no longer recorded in ReservationTracker, and ReservationTracker will be removed later;
