feat: Add support for Azure CNI (w/o overlay)

[Bryce-Soghigian]

Tell us about your request

Karpenter users should be able to use the Azure CNI without overlay networking.

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?

Currently the only part that karpenter needs to do differently for this support is to generate additional ip configurations for IPAM to consume on the nics we create.

@Bryce-Soghigian I just want to thank you for this work you are doing. I honestly can't wait for this to be done 😄

this is a blocker issue for us. Azure Application Gateway cannot be used when azure-cni with overlay is enabled. hopefully it gets resolved soon.
