New Integration Test

[jdubpark]

New integration test that simplifies logic and makes changes much easier.

This Integration Test is tested on main b0aee07 merged with cherry-picked test 46eed8c..af5eada.

The purpose of this PR from a new branch over the test branch is to reduce the PR size. The test branch has gone through extensive rebasing in the last few days with breaking PRs, thus the commit history is too large for PR. Instead, this new branch introduces all the necessary changes of the test branch in a slim commit history.

• Introduce the Big Bang integration, which replaces the old Integration test. All interactions will be tested in the big-bang folder, and NO mocks are allowed (except PolicyFrameworkManagers).
• Introduce a shared integration framework that makes framework managers and policies more extensible—readying for permutation tests.
• Structure the integration folders for future integration and flow tests.
• Add fixes and changes to make the integration test work on main b0aee07.
