This code snippet is measuring time to enqueue a request to ZooKeeper
client. "endTimeWrite" needs to be set after the operation completes.
Register a listener to the curator client and set endTimeWrite in the
eventReceived callback. It looks like you are already passing the
start time as a context. You can access the start time in the callback
by calling CuratorEvent.getContext().
