    Attachment: SOLR-5823.patch

Here's a quick patch with a happy path assert added to the ZkControllerTest.
This solution currently is doing some parsing of the znode data retrieved from ZK to isolate the node name. Looks like the ZooKeeper folks are planning to introduce a Path class to help with parsing in 3.5 (see: https://issues.apache.org/jira/browse/ZOOKEEPER-849) but not available yet so I'm just parsing out the node name from the znode sequence id.

> It would be useful if there was some Overseer equivalent to CloudDescriptor.isLeader() that plugins running in solr could use to know "At this moment, am i the leader?"
