    ZOOKEEPER-2759: Flaky test: org.apache.zookeeper.server.quorum.QuorumCnxManagerTest.testNoAuthLearnerConnectToAuthRequiredServerWithHigherSid

    I noticed some inconsistent test results from `testNoAuthLearnerConnectToAuthRequiredServerWithHigherSid`.
It can be seen failing on Apache infra here: http://mail-archives.apache.org/mod_mbox/zookeeper-dev/201701.mbox/%3c374175863.2852.1485127554310.JavaMail.jenkins@crius%3e
    The problem can be "reproduced" by adding a `Thread.sleep(4000)` as the first line of
the finally block   for `RecvWorker.run` in `QuorumCnxManager.java`.
    The issue is caused by a race condition between the removal of the relevant `sid` from
`senderWorkerMap` for `peer0` and the 3 second delay from `assertEventuallyNotConnected`.

    Other tests in this class do not experience the same problem because `testNoAuthLearnerConnectToAuthRequiredServerWithHigherSid`
is unique in that it is the only test using `assertEventuallyNotConnected` where the peer
with the lower `sid` is not using SASL. This means that the peer with the lower `sid` will
always create send and receive workers in `handleConnection` (as it will not throw an exception
on `authServer.authenticate(sock, din)`) and may not destroy them in time for the test assertion.
