 	// PreferredStrategies indicates the list of strategies for picking the leader for coordinated leader election.
 	// The list is ordered, and the first strategy supersedes all other strategies. The list is used by coordinated
 	// leader election to make a decision about the final election strategy. This follows as
 	// - If all clients have strategy X as the first element in this list, strategy X will be used.
 	// - If a candidate has strategy [X] and another candidate has strategy [Y, X], Y supersedes X and strategy Y
