@dwoz, @garethgreenaway, @twangboy Can you take another look when you get a sec 😃

The lint stage is failing because of unrelated changes, but all tests are passing now.

We should actually run this against the cloudtests, doing that here: #58248

The links are wierd because github records statuses by commit, rather than commit on a pr.

Also, all of the class docs show up in the html docs which makes them not too pretty. I think there's a flag in sphinx to hide them, but I can't remember what it is.

no linode cloud test failures, so we're good there.

Test Result (8 failures )

    integration.cloud.clouds.test_ec2.EC2Test.test_instance
    integration.cloud.clouds.test_ec2.EC2Test.test_instance_rename

which is the same as the master branch currently.

@Akm0d @sagetherage @bryceml Anything I can do to get this merged?

[sagetherage]

I believe we have been working to fix test failures (outside of this PR) before merging new code, so it seems we are delayed or forgetful, however the team is focused on fixing test suite issues so merging is smoother in the near future. That being said, I will see about this today and early next week to get it merged. Thank you for the mention!
