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.		2017-05-02 18:21:37 -05:00
