Out Scripts are Optimized in the Importing Task

[lnxpy]

isort module observed on the outer scripts. So that neither search/*.py, lib/*.py, datasets/*.py, and utils/*.py have been changed which means that the schema2search_space.py file is still like the usual.

Thanks, happy to see that this version passes Travis. Also, I read through the code changes, and they look good to me. Could you please sign a DCO as outlined in contributing.md? You can email it to me: hirzel at us dot ibm dot com.

[lnxpy]

That's my pleasure. Should I send the DCO doc back to you? Is it enough or any other significant required?

[hirzel]

Yes, could you please email the signed DCO back to me?

[lnxpy]

Everything is done. Special thanks to you for checking out the PRs. Really appreciate your attention. I really amazed by the name of the project; just because my native language is Persian. ❤️✌️

[lnxpy]

Hey dear @hirzel,
Do you mind if I ask you to first, review this PR and finally, add the "hacktoberfest" label to this pull request?
Thanks.

[hirzel]

The changes sort import statements in Python files that are directly in the main lale directory. There are no changes to the code outside of those import statements. The Travis tests succeeded.

[lnxpy]

Thanks. I'll contribute to the main algorithm and add new features soon.

thanks for contributing this and getting this started! Continuing on this work, #481 resolved the issue with schema2search_space.py, ran isort on everything, and added isort to our new pre-commit setup.
