Description

This PR now allows us to check all our Python files with flake8.

The excluded files have been cleaned up and formatted with black.

"By using Black, you agree to cede control over minutiae of hand-formatting. In return, Black gives you speed, determinism, and freedom from pycodestyle nagging about formatting. You will save time and mental energy for more important matters.

Black makes code review faster by producing the smallest diffs possible. Blackened code looks the same regardless of the project you’re reading. Formatting becomes transparent after a while and you can focus on the content instead."

How Has This Been Tested?

First ran black on the excluded files.

Then ran: pre-commit run --all-files and the flake8 test passed.

How did you try to break this feature and the system with this change?

@DaanHoogland @jbampton should we add black as a pre-commit hook? I have been thinking of fixing formatting for our tests and marvin lib as well. Not in this PR, but a separate PR for that.

[jbampton]

Hey @vishesh92 I added black pre-commit on Apache Sedona here:

apache/sedona#1593

There are a lot more pre-commit hooks we can add to CloudStack including black.

I was waiting for some of my PRs to be merged before adding more pre-commit hooks
