Explicitly state Load Balancer Secondary IP Usage

It should be explicitly stated on the documentation that Secondary IPConfigs are not usable for Outbound Rules on a Public Load Balancer. 

Reading the first 3 dot points regarding the use of a Load Balancer, configuring everything, only to find that SecondaryIPs are not supported: https://docs.microsoft.com/en-us/azure/load-balancer/outbound-rules#limitations
> Outbound rules can only be applied to primary IP configuration of a NIC. You can't create an outbound rule for the secondary IP of a VM or NVA. Multiple NICs are supported.

 Every NIC attached to a VM has one or more IP configurations associated to it. Each configuration is assigned one static or dynamic private IP address. Each configuration may also have one public IP address resource associated to it. A public IP address resource has either a dynamic or static public IP address assigned to it. To learn more about IP addresses in Azure, read the [IP addresses in Azure](../articles/virtual-network/ip-services/public-ip-addresses.md) article.
 
 > [!NOTE]
 > All IP configurations on a single NIC must be associated to the same subnet.  If multiple IPs on different subnets are desired, multiple NICs on a VM can be used.  To learn more about multiple NICs on a VM in Azure, read the [Create VM with Multiple NICs](../articles/virtual-machines/windows/multiple-nics.md) article.
