Space instance recovery fails on "Failed while getting participants from zookeeper server"

Backup Space instance failed during a recovery attempt due to an IllegalStateException thrown from the Curator framework. This is caused by the closing of the attribute store done as part of bug fix GS-13502.

The fix for is to close the ZooKeeper attribute store, which in turn closes the Curator framework - shared by the attribute store and the leader selector. Due to this dependency, we got the following exception: "Failed while getting participants from zookeeper server: java.lang.IllegalStateException: instance must be started before calling this method".
