Update the existing load API to introduce a "load owner" concept. This allows the tracking of the loaded configurations and features against the loading owner type, to allow later unload according to owner. A list of loaded configurations by owner is created. The load owner infrastructure will be used in following patches to implement dynanic load and unload, alongside dependency tracking.
