[FLINK-2696] [test-stability] Hardens
ZookeeperOffsetHandlerTest.runOffsetManipulationinZooKeeperTest
The test case
`ZookeeperOffsetHandlerTest.runOffsetManipulationinZooKeeperTest` failed,
because the ZooKeeper client could not connect to the ZooKeeper server. I
suspect that this might be caused by contention of multiple test cases for the
same port to bind to. Internally, Curator's `TestingServer` is started with a
port which has been determined using `NetUtils.getAvailablePort`. Since the
port is not directly bound, it is possible that another process uses the
determined port and, thus, preventing the `TestingServer` from starting.

[FLINK-2696] [test-stability] Hardens ZookeeperOffsetHandlerTest by letting
Curator's TestingServer select the port to bind to instead of using
NetUtils.getAvailablePort.
