tests are much more noisy after logviewer autolaunching change #216

As part of logviewer autolaunching we added a wrapper around the Apache Curator library for our code to directly manipulate state in ZooKeeper. This resulted in a bunch of noisy log lines during the maven tests, looking like the following:

9984 [main-SendThread(localhost:2181)] WARN  o.a.z.ClientCnxn - Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect
java.net.ConnectException: Connection refused

We should look into leveraging the in-process ZooKeeper server that seems to be launched:

10213 [main] INFO  s.m.u.ZKClient - Attempting to connect to following ZooKeeper servers: 127.0.0.1:51046
10213 [main] INFO  o.a.c.f.i.CuratorFrameworkImpl - Starting
