Michi Mutsuzaki updated ZOOKEEPER-1870:
---------------------------------------

    Description: 
I'm seeing lots of the following failure. Seems like a flakey test (passes 
every so often).

{noformat}
junit.framework.AssertionFailedError: client could not connect to reestablished 
quorum: giving up after 30+ seconds.
        at 
org.apache.zookeeper.test.ReconfigTest.testNormalOperation(ReconfigTest.java:143)
        at 
org.apache.zookeeper.server.quorum.StandaloneDisabledTest.startSingleServerTest(StandaloneDisabledTest.java:75)
        at 
org.apache.zookeeper.JUnit4ZKTestRunner$LoggedInvokeMethod.evaluate(JUnit4ZKTestRunner.java:52)
{noformat}

I've found 3 problems that 

1. Prevent socket leak in QuorumCnxManager.Listener.run().
2. Make QuorumCnxManager.halt() join the listener.
3. Reset QuorumPeer.shuttingDownLE flag when restarting the leader election.
