Copyright notices are missing for some Python scripts

[terrytangyuan]

We have good coverage on copyright notices at the top of each files in https://github.com/couler-proj/couler/tree/d34a690/couler/core but many are still missing, for example:

• https://github.com/couler-proj/couler/tree/d34a690/couler/steps
• https://github.com/couler-proj/couler/tree/d34a690/couler/tests

Thanks @terrytangyuan! Unable to push to the repo to raise a PR right now. Would you be able to help me with this?

You would need to push to your forked repo and then submit a PR from there: https://docs.github.com/en/free-pro-team@latest/github/getting-started-with-github/fork-a-repo
