Stephan Erb 0b9fca983b Fix reload of ZooKeeper service discovery config (#2669)
Rational:

* When the config is reloaded and the provider context is canceled, we need to
  exit the current ZK `TargetProvider.Run` method as a new provider will be
  instantiated.
* In case `Stop` is called on the `ZookeeperTreeCache`, the update/events
  channel may not be closed as it is shared by multiple caches and would
  thus be double closed.
* Stopping all `zookeeperTreeCacheNode`s on teardown ensures all associated
  watcher go-routines will be closed eagerly rather than implicityly on
  connection close events.
