	mgr, err := ctrl.NewManager(ctrl.GetConfigOrDie(), ctrl.Options{
	Scheme: scheme,
	Metrics: metricsserver.Options{BindAddress: metricsAddr},
	HealthProbeBindAddress: probeAddr,
	LeaderElection: enableLeaderElection,
	LeaderElectionID: "fbb36db9.llmaz.io",
	// LeaderElectionReleaseOnCancel defines if the leader should step down voluntarily
	// when the Manager ends. This requires the binary to immediately end when the
	// Manager is stopped, otherwise, this setting is unsafe. Setting this significantly
	// speeds up voluntary leader transitions as the new leader don't have to wait
	// LeaseDuration time first.
	//
	// In the default scaffold provided, the program ends immediately after
	// the manager stops, so would be fine to enable this option. However,
	// if you are doing or is intended to do any operation such as perform cleanups
	// after the manager stops then its usage might be unsafe.
	// LeaderElectionReleaseOnCancel: true,
	})

hi, from the code point of view, LeaderElection is currently supported to support HA. Are there any other requirements? would you mean to add more replica nums?

Thanks @qinguoyi for pointing it out, that's true. Then what we left is just make it configurable with helm chart, as well as the Replicas of the controller, here's the values.yaml: https://github.com/InftyAI/llmaz/blob/main/chart/values.global.yaml

Would you like to finish the work? That would be really appreciate, I think it wouldn't take a lot of time.
