When leader election is enabled, a non-leader manager would never start the LeaderElection runnable group. Thus, as the shutdown process calls the sync.Once Start func of the runnableGroup; it will start a new election. This change ensures `Start` is ineffective during shutdown. The test ensures the LeaderElection runnableGroup is not started during shutdown. Signed-off-by: Alexandre Mahdhaoui <[email protected]>
