The support for delta_root allows to build a delta container image from a given base container. Due to the refactoring of the kiwi code base using context managers no explicit deletion of instances happens anymore. This uncovered a weakness of the delta root code at the level of the overlay mount. At the time of the umount there are still active temporary mount handlers which keeps the mountpoint busy. In order to fix this properly also the PackageManager factory is now a context manager and the Repository factory received a cleanup method which is called when the PackageManager goes out of scope. This refactoring also fixes the busy state when building deltas
