This PR allows scope: cluster on standalone CRDs, and thus allowing to be installed in the /etc/deployment-apps dir

Key Changes

• Modifying standalone CRDs to allow scope: cluster (as well as scope: local, where behavior is unchanged)
  • This will now allow us to install to /etc/deployment-apps

Testing and Verification

Ran operator and automation locally, however still in the process of manually verifying the changes. Just creating this PR to start getting review on work.

It would be good to add a test case to the appframeworksS1 test suite that includes an app deployed to the cluster scope, or possibly even add to one of the existing test cases with the cluster scope for a new app.

There are also some existing unit tests in standalone_test.go that are related to appframework that we should add to as well to test both the local and cluster scoped apps.

I agree. We need to add new test cases. Also, I believe that automated tests are not enough and some portion of manual tests is required for both local and cluster scopes.

I suggest including documentation similar to #1603 for how to handle serverclasses and the new clusterscope for etc/deployment-apps together.
