This flaky test had happend many times found by ZOOKEEPER-2913 and
ZOOKEEPER-3040 reported by Patrick Hunt
The build failed report url about it is
[here](https://builds.apache.org/job/ZooKeeper_branch34_java9/305/testReport/junit/org.apache.zookeeper.server.quorum/EphemeralNodeDeletionTest/testEphemeralNodeDeletion/)
which now is broken.
When Jenkins does regression,it will happen again.If you have more
concerns,let this patch still,and waiting for this flaky test coming back :D
