With dnf5 there is a successor for dnf but there will also be a transition period where there will be both, the former dnf and the new dnf5 available. For a clear distinction between the two we got the recommendation from the RedHat team to support both in different namespaces. This commit now implements a backward compatible change for kiwi which includes the following modifications: * XSL stylesheet for automatic schema transformation from <packagemanager>dnf</packagemanager> to <packagemanager>dnf4</packagemanager> * Code copy of dnf API interface from PackageManagerDnf -> PackageManagerDnf4 RepositoryDnf -> RepositoryDnf4 * Deprecation of former Dnf API interface The code change here will force developers to adapt their code if they used RepositoryDnf / PackageManagerDnf classes in their python code. After this change developers will be dropped into a raise condition which exits kiwi at the time of the call. Related to Issue #2300 and Issue #2262
