The KafkaJolokiaCollector should be able to collect from a replicated cluster of Zookeeper nodes #67
Description
The KafkaJolokiaCollector only permits one zookeeper node to be configured. If that node goes down for some reason the instance is then not able to collect zookeeper metrics such as CollectorLag until the zookeeper instance is brought back.
The collector should permit the specification of multiple nodes in the config and, ideally, use some logic to retry collections against secondary or tertiary nodes if available.
