    ZOOKEEPER-2692: Fix race condition in testWatchAutoResetWithPending

    We occasionally run into an issue with testWatchAutoResetWithPending where we get flaky
test behavior due to not being able to reliably predict when the client has received notification
from each watch that may be fired (perhaps due to resource contention on the box running the
tests). This patch works around that by waiting for a one second quiet period, after which
we can more safely assume all watches that will be fired have been fired.
    
    Here is an example of the test failure: https://builds.apache.org/job/ZooKeeper-trunk-jdk8/935/testReport/junit/org.apache.zookeeper.test/WatcherTest/testWatchAutoResetWithPending/
