PublicIPPrefix: Allow exporting IP range as ConfigMap

[felfa01]

Describe the current behavior
In my setup I'd like to configure NetworkRules for a Storage Account. For that I'd require outputting the allocated IPs from an ASO-created PublicIPPrefix and input that to the ASO-generated Storage Account network rules.

The same pattern can be seen with User Assigned Identities and Role Assignments.

We discussed this and it seems like a pretty reasonable ask. I believe we already have support for the infrastructure required to do this in the azure-arm.yaml file of the ASO code generator.

At least the output step will be solved by #2555.
