PR Summary

• Removal of Specific Fields from PlanProfile Structure
  Several attributes or fields from the 'PlanProfile' data structure namely cpu_time, wait_time, exchange_rows, and exchange_bytes have been removed. This essentially means that the data related to these aspects won't be stored in the structure anymore.

• Update to load_profile and merge Functions
  Corresponding changes have been made in two functions: load_profile and merge as part of the 'PlanProfile' block. Specifically, those parts of code in these functions that dealt with the aforementioned fields have been taken out. The functions will now work without considering these parameters, leading to a slightly different way of executing tasks.
