How Has This Been Tested?

[DaanHoogland]

@jbampton are you running these tests locally? they are not run in any of the travis jobs.

[jbampton]

Yes I run flake8 locally. But it runs with the GitHub Actions SuperLinter Check on modified files only on pull requests:

https://github.com/apache/cloudstack/actions/runs/3454836056/jobs/5766433087

[jbampton]

In future we could add flake8 to pre-commit to allow everyone to run the tests locally on git commit.

There is another pull request where I was adding the first check with pre-commit.

daring to go against principle on this one, only empty lines on end of files
