I am able to run `./tools/toolchain/dbuild ./build/release/scylla --developer-mode 1` , but if removed `--developer-mode 1`, it will require me to run `scylla_io_setup`.  
> Now if I directly run `./tools/toolchain/dbuild ./dist/common/scripts/scylla_io_setup` I will get an error `ModuleNotFoundError: No module named 'scylla_product'`. I assume `scylla_product.py` is created by some other install scripts? **My question is: Is there any easy way for me to run such a quick benchmark with I/O properly configured?**
