Azure Event Hub Authorization Rule Created or Updatededit

Identifies when an Event Hub Authorization Rule is created or updated in Azure. An authorization rule is associated with specific rights, and carries a pair of cryptographic keys. When you create an Event Hubs namespace, a policy rule named RootManageSharedAccessKey is created for the namespace. This has manage permissions for the entire namespace and it’s recommended that you treat this rule like an administrative root account and don’t use it in your application.
