Bug fixes:
- Fixed ZooKeeper installation manifests that did not mount PV properly. The bug could result in ZooKeeper data loss if ZK pods were restarted.
- Fixed metrics exporter to work across multiple ClickHouse versions -- metric descriptions are temporary removed, Prometheus does not work good if those change.
Other changes:
- Bumped prometheus/golang_client to the latest version
- Added extra logging into chi status field.
