* Support mechanism to provide external zookeeper-server list to build global/configuration zookeeper * Add external zk example * add external zk list into values.yaml Fixes #268 ### Motivation Right now, [chart dynamically](https://github.com/apache/pulsar-helm-chart/blob/master/charts/pulsar/templates/zookeeper-statefulset.yaml#L140) creates zk cluster with zk pods initialized in the same namespace. However, for global/configuration zookeeper, user requires to build zk clusters with pods deployed in different namespaces. Therefore, user needs a mechanism to pass an external list of zk-servers to the chart and build zk-cluster with pods across different namespaces. ### Modification - Chart should be considering zk-value's configuration for external zookeeper and generate zk-configuration file with appropriate zk-server list and unique id of that zookeeper. This PR sets `ZOOKEEPER_SERVERS` value provided by user and also sets override-value flag which will be used by [generate-zookeeper-config.sh](https://github.com/apache/pulsar/blob/master/docker/pulsar/scripts/generate-zookeeper-config.sh) to override external zk list in config file and assign appropriate id to the host. https://github.com/apache/pulsar/pull/15987 fixes [generate-zookeeper-config.sh](https://github.com/apache/pulsar/blob/master/docker/pulsar/scripts/generate-zookeeper-config.sh) changes. ### Result - User can add `ZOOKEEPER_SERVERS` string into `zookeeper.configData` in [Values.yaml](https://github.com/apache/pulsar-helm-chart/blob/master/charts/pulsar/values.yaml#L385) file to override external zk-server list.
