Defines a stub storage.
This storage is always empty; the controller reads and writes nothing.
The stub implementation is needed for synchronizing configuration during installation of a module, in which case all configuration being shipped with the module is known to be new. Therefore, the module installation process is able to short-circuit the full diff against the active configuration; the diff would yield all currently available configuration as items to remove, since they do not exist in the module's default configuration directory.
This also can be used for testing purposes.
