Controllers are all singleton despite dependencies having SCOPE.REQUEST

Describe the bug
A clear and concise description of what the bug is.

For now, Controllers are singleton;

Expected behavior

Controller whose one or more dependencies have SCOPE.REQUEST should be instantiated on every request.

We need to add metadata on the controller that tags it as "SCOPE.REQUEST" when injecting its dependencies. Then when adding it to resolved map, either uses a singleton or a factory.
