Description

Currently zookeeper related infos, like zk path, curator client, are scattered many places, like
ZookeeperDistributedLock, DistributedScheduler, CuratorScheduler. It's better to centralize them. There'll be several benefits:

• Avoid creating multiple curator clients
• Easy to manage the zk path by leveraging zkChRoot
