Remove centos rsync mirroring tooling

Now that CentOS 7, 8 and 8-stream have been removed from mirroring we
can drop the mirror script for these releases entirely. Note that
9-stream and beyond use the newer centos-stream script instead and are
not affected.

Once this is completed we should be able to clean up the afs volume for
centos entirely as well (though it is empty currently and has a very low
cost in that state).
