proposal: Move all top-level methods to groups and correct documentation

[lgarber-akamai]

📝 Description

This change moves all top-level methods (LinodeClient.nodebalancers(...), etc.) to groups to ensure consistency with the rest of the project. Additionally, alias methods have been created to prevent introducing any breaking changes and to ensure backwards compatibility.

Top-level list methods are now implemented as __call__(...) methods for group classes, and create functions have been moved to create(...) methods inside of each group.

These groups have all been moved to a separate groups package which significantly reduces the size of the linode_client package.

This change also introduces a few fixes for documentation issues:

• The sidebar width has been slightly increased to prevent content on the sidebar from overlapping with page content
• The page width has been slightly increased to improve readability
• Groups that were previously missing from the documentation have since been added

✔️ How to Test

Testing refactor changes:

tox

Testing docs changes:

I just pushed up an implementation I'm much happier with. I'd love to hear some thoughts 🙂

Tests are passing locally! I think this is a much better structure for the project. It's less clunky and much easier to track down where changes should go. Good work!

Nice refactor!

Great work! Once your change merged, I'll rebase it and refactor the obj group that I'm working on.
