xt_cluster supersedes ipt_CLUSTERIP since it can be also used in gateway configurations (not only from the backend side). ipt_CLUSTER is also known to leak the netdev that it uses on device removal, which requires a rather large fix to workaround the problem: http://patchwork.ozlabs.org/patch/358629/ So let's deprecate this so we can probably kill code this in the future.
