I think these belongs to the global gas schedule because:

1. they are not changed per epoch, like the per epoch updating prices, so there's no concern writing a large struct from move frequently.
2. the global schedule has support to add new parameters. I can imagine we might need free_items_to_write_per_txn etc.
