Description

Summary of Changes

This PR migrates the integration tests for crud/crud_api. The changes include:

• Refactor callbacks to async/await
• Direct import from the src folder
• Removing old test requirements (for example, for mongodb >= 3, or topology "ssl")
• Changing some independent tests within the single it into separate describe with multiple tests in it

Notes for Reviewers

The file is huge, and there are many changes in it, but I tried to keep the same structure, I hope it's still manageable to review it. Let me know if you want me to break down PR into pieces somehow.

What is the motivation for this change?

This work is part of a larger, ongoing initiative to convert all tests to use async/await, with the ultimate goal of removing the legacy driver wrapper.

thanks for the review @baileympearson, I addressed all the comments, you are right, couple of tests should just be removed, and the metadata requirements can be lift off for the current setup.
