Taking long to review even if I leave out the test_data/expected need more time to ramp up

if we are using the same framework as upstream, I am wondering if it is possible to keep only the diff here. Integration tests and overlays depend on the upstream repo to be available locally, Can we use the same approach and only keep a diff we own?

PR mentions awsconfigs/common. will tests for awsconfigs/apps be a separate PR? It will be good to keep it separate

Yes, it will be a separate pr, this was to port things under common since they are all aws related.

Can you link to the original PR in the description since that PR had easier to read diffs for reference.

LGTM since this is a copy of the previous PRs changes with path changes.
