[Testing Confirmation] Confirm current testing requirements

[stephen-crawford]

As part of the discussion around implementing an organization-wide testing policy, I am visiting each repo to see what tests they currently perform. I am conducting this work on GitHub so that it is easy to reference.

Looking at the Observability repository, it appears there is

Repository	Unit Tests	Integration Tests	Backwards Compatibility Tests	Additional Tests	Link
Observability				Link checker, Certificate of Origin, Enforce PR Labels	#1416

I don't see any requirements for code coverage in the testing documentation. If there are any specific requirements could you respond to this issue to let me know?

I also noticed you had a Trace Analytics workflow, but I was not sure if that was still being run.

If there are any tests I missed or anything you think all repositories in OpenSearch should have for testing please respond to this issue with details.
