Colin Patrick McCabe b67a3fa79d KAFKA-16509: CurrentControllerId metric is unreliable in ZK mode (#15695) ... The CurrentControllerId metric added by KIP-1001 is unreliable in ZK mode. Sometimes when there is no active ZK-based controller, it still shows the previous controller ID. Instead, it should show -1 in that situation. This PR fixes that by using the controller ID from the KafkaController.scala, which is obtained directly from the controller znode. It also adds a new test, ControllerIdMetricTest.scala.
