Please refactor elb_classic_lb_info to make our code easier to understand, in particular:

• Break each function down into smaller scoped functions.
• Add documentation to each function to clarify what it does.
• Ensure that each method has type hints so that it is clear what a given method returns.

Make sure you are following our coding guidelines: https://github.com/ansible-collections/cloud-content-handbook/blob/main/GUIDELINES/coding_guidelines.md#coding-standards

Definition of Done
