Yup, it was easy to move annotations handling to plain MetaData lookup. :-)

I also (re)moved the part in PreInstallAction where MetaDataRetrieval was referenced from KernelMetaDataRepository.

But I guess this code cannot be changed to use plain MetaData since I _need_ to build the whole MetaDataRetrieval for the scope - similar to how we do it for ControllerContext's MetaData (hidden in BasicKernelMetaDataRepository).
