Always write new cluster state versions to ZooKeeper
Previously, the controller would not write the version to ZK unless the
version was published to at least one node. This could lead to problems
due to un-written version numbers being visible via the controller's REST
APIs. External observers could see versions that were not present in ZK
and that would not be stable across reelections. As a consequence, invariants
for strictly increasing version numbers would be violated from the
perspective of these external observers (in particular, our system test
framework).
