Make a package that updates packages from old version to new version

[Konard]

PackageQuery |-- Update --> PackageQuery

This link should trigger update of old package with new. It is actually a replacement, old package is deleted in the result.

We need to find how all links from old package are used and replace them with corresponding link from new package (if the same name exists) using deep.update operation. If new package does not have all links that are used in old package, the error should be thrown. Error checking should be done before any changes.
