Currently, CAPZ only allows a single API load balancer to be specified. OpenShift requires both a public and private load balancer. It is desirable to allow multiple load balancers to be specified in the API load balancer field.

We need to modify the Azure CAPI NetworkSpec to add support for an array of load balancers. For each LB in the array, the existing behavior of a load balancer needs to be implemented (adding VM's into the backend pool).
