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.
