Research direction
No file or test is named. Start by locating ZookeeperServiceWatch and its tree-cache setup, then trace how service-discovery configuration is loaded; done means a configuration switch can prevent the watcher from being enabled without breaking the existing service-discovery path.

ZookeeperServiceWatch create a treecache to iterate watch /services dir, when service and service instance num increase high，the watcher num will increase dramatically as instances watch the path each other
e.g. service num is 500, instance num is 2500, the watch number will be (500 + 2500) * 2500 * 2= 15m ,multiply 2 as
path data and path children will be both watched
