Method to disable evaluation

[Zhi Cheng Lee]

Just sharing here. While attempting to disable evaluation, I find that setting only do_eval: False is unable to turn it off.
After studying the code, it appears that both do_eval: False and evaluation_strategy: "no" need to be set in order to fully disable evaluation.
