User Story:

As a (user persona), I want to be able to:

• Support both IPv4 and IPv6 backend address pool configurations

so that I can achieve

• Dual stack networking support on Azure

Acceptance Criteria:

Description of criteria:

• Backend address pool support for IPv4 and IPv6

Engineering Details:

• The API internal load balancer spec is created here: https://github.com/openshift/installer/blob/0ed55cf610c7b8812ccfebd51350e31ae43e8259/pkg/asset/manifests/azure/cluster.go#L88
• The spec only supports a single backend address pool when created by CAPZ
• The load balancer is later updated after creation here: https://github.com/openshift/installer/blob/0ed55cf610c7b8812ccfebd51350e31ae43e8259/pkg/infrastructure/azure/azure.go#L538
• This function will need to be updated to add any additional backend address pools
