Revert introduction of adaptive pack-objects limiter
In 023c2a7d (Merge branch 'qmnguyen0711/add-adaptive-limit-to-pack-objects-limit' into 'master', 2023-08-09), we have introduced new code to add an adaptive limit to pack-objects. This new limiter is seemingly creating a memory leak that causes issues in production systems.
Revert this merge request.
