Subject: [PATCH] Run zookeeper datadir on tmpfs during testing

We may be experiencing iops performance issues resulting in unreliable
tests due to broken zookeeper connections. Run zookeeper under tmpfs to
mitigate this problem.

Other alternatives include using a system like eatmydata to make write
return early.
