We have made many improvements to connection handling in Zuul. Bring those back to Nodepool by copying over the zuul/zk directory which has our base ZK connection classes. This will enable us to bring other Zuul classes over, such as the component registry. The existing connection-related code is removed and the remaining model-style code is moved to nodepool.zk.zookeeper. Almost every file imported the model as nodepool.zk, so import adjustments are made to compensate while keeping the code more or less as-is. Change-Id: I9f793d7bbad573cb881dfcfdf11e3013e0f8e4a3
