> This change allows the REST interface to publish its endpoint and metrics, currently only requests/sec, into ZooKeeper. By default a permanent znode tree is created as needed at {{/hbase/rest/status}} and Stargate instances create ephemeral children of this with names in the format {{<host>:<port>}}. The ephemeral znodes contain JSON serialized information about the instance, e.g.
>     {{{"connector":{"host":"restserver.example.com","port":"8080"},"statistics":{"requests":"13"}}}}
> The function of Stargate itself is not affected, except for one significant change: now if the ZooKeeper service is lost, the Stargate instances will abort along with the rest of HBase.
