Reduce technical debt of code duplication in automated tests

[arrestle]

1. Updates to remove duplicate code and share constants and variables.
2. Updates to the Makefile to add help, allow local linting through local .tools folder, remove hardcoded AAP_HOST.

Thanks for getting this in so early @arrestle.

I've skimmed the refactoring in the _test.go and utils files, and that looks good. Just a couple of points there. I also ran the acceptance tests locally before/after and confirmed the test coverage has not decreased. I would appreciate if others could weigh in as well on the refactored logic.

I'm requesting changes on two specific areas:

1. There are changes in the README and Makefile around what to run to support the acceptance tests. I think we'll be addressing that in a future ticket around contribution guidelines, so I don't think we're ready for this change and my request is that we hold these back.
2. There are additions to GetWithStatus that enhance error checking. I had some specific feedback on individual checks as well and some general refactoring feedback. The ask here is to review these checks and see what can be refactored, removed, or changed so that details aren't lost.

Lets collapse the Makefile target into one and use environment variables to set it up.

Thanks for addressing the feedback. LGTM.
