Using map names with forward slashes (`/` character) returns empty childData

Observe that if the user supplies a map key that contains forward slashes, empty data will be returned from Zookeeper due to this split.

Do you have a reproducer?

Simply create a map named Test/map.

Emm..

We can replace forward slash which in input with empty string from vertx-zookeeper, but can not replace it from other input, such as zkCli.sh I will make PR to fix it.

One possibility is to throw an IllegalArgumentException that is implementation specific, so that at least people don't get an extremely cryptic crash (it right now fails to deserialize an empty object)
