About Zookeeper version
We use Curator 4.3.0, as Zookeeper latest stable is 3.4.8 so we do not support any features of 3.5.x

Version

4.0.2

Context

when i use zookeeper server 3.4.6，and i use vertx-zookeeper 4.0.2 . it report some errors,like :

17:14:36.527 [vert.x-worker-thread-0] ERROR o.a.c.f.imps.CuratorFrameworkImpl - Ensure path threw exception
org.apache.zookeeper.KeeperException$UnimplementedException: KeeperErrorCode = Unimplemented for /io.vertx

and when i change zookeeper server from 3.4.6 to 3.5.9 ,it works .

so i think ,the document was error.need to update!!!!

Extra
