This enables atomic updates to the repository metadata on the server
side, which should mitigate some of the issues we’ve seen with bad
hashes for packages.
* Move to using CPack for repository configuration packages.
This simplifies testing of changes to the configuration itself, as well
as making package builds marginally faster.
* Fix CMake handling for old RPM distros.
* Fix openSUSE detection.
* Fix file installation.
* Override code ownership for packaging/repoconfig/CMakeLists.txt
This way changes won’t bother people who aren’t actually responsible for
it.
* Update CI skip logic to work correctly with new repoconfig setup.
* Add improved status messages.
