> A recent change to SchedulerLifecycle introduced a regression where leadership announcement never happens.  This is because a singly-threaded ScheduledExecutorService is injected into SchedulerLifecycle, and SchedulerLifecycle invokes the blocking driver.join().  This prevents the delayed operation to announce leadership from ever executing.
