This adds the following test:
1. cluster comes up (node 1,2,3), status normal
2. Pause node 3
3. Insert keys making sure to filter out the keys that will go to the paused node
4. Wait for status to become degraded
5. Unpause node 3
6. Wait for status to get back to normal
7. Check that keys were replicated to all 3 nodes
