Key changes:

• Adds new CLI commands az aks applicationloadbalancer enable/disable/update for managing the addon
• Integrates the addon into existing addon management infrastructure (aks addon enable/disable)
• Stores configuration in the cluster's ingress profile rather than the standard addon profile
