Refactor security config spec

What does this MR do and why?

There is a lot of repeated code, I am refactoring this spec file so it's more DRY. This change is based on the comment made here and the effort intially done by @dftian 👍 > !86639 (comment 935872934)

augmentedSecurityFeatures and augmentedComplianceFeatures were being provided in every test, so I just made them the default.
