CURATOR-114 - Modified the TestingServer to expose the restart() method
on the underlying TestingZooKeeperServer. Modified all unit tests that
were previously using the stop() and then recreate using existing
temporary directory and port approach for restarting the server, so that
they now just call the restart() method.
CURATOR-114 - Modified the restart() method so that it will restart the
server from any state other than CLOSED (because this server has had all
of its state cleared).
