GlobalRefresher (Couchbase JVM Core IO 2.4.9 API)

java.lang.Object
- com.couchbase.client.core.config.refresher.GlobalRefresher

```
public class GlobalRefresher
extends Object
```
The GlobalRefresher keeps the cluster-level global config up-to-date.
It works very similar to the KeyValueBucketRefresher, but explicitly has no bucket level scope. It can be started and stopped, since there might be situations where global config polling is not needed.
