Support a service tag which denotes the IP address space for Azure Automation
Currently, we don't support a service tag which denotes the IP address space for Azure Automation service. There are scenarios where a customer would like to allow only the inbound traffic from Azure Automation service by using NSG when a runbook send a HTTP request to a VM. Such customers are requires to whitelist all IP addresses of Azure datacenter. However the customers need to update the settings of NSG every week because there's a possibility that the Azure IP ranges are changed once a week. This requires complicated procedures and high-maintenance. So, it would be great if the service tag for Azure Automation service is supported so that a customer can omit the complicated process, which is updating the settings of NSG every week.
