make, lint: Limit use of OncePerOrderedCleanup The OncePerOrderedCleanup label was introduced in https://github.com/kubevirt/kubevirt/pull/13786 as a pilot for SIG-Network and virtctl. Its purpose is to enable sharing of VMs between multiple tests thus reducing test duration and resource usage. Since the feature is temporarily only allowed in the above areas, this commit adds a linter that fails the lint process should a file located elsewhere use the label. If additional files/areas would like to participate in the pilot, please add required file or directory to the EXCLUDE_PATTERN variable. This entire commit is expected to be reverted once the whole project is on board. Signed-off-by: Nir Dothan <ndothan@redhat.com>
