This adds support for finding subnets tagged with
kubernetes.io/role/internal-node
and expose them a.Values.internal_node_subnets
in templates.The purpose of this is to be able to discover and launch a subnet of node pools in internal subnets. This is useful for special instances running with NAT gateways or simply for running nodes in internal subnets.
A concrete use case is getting p5.48xlarge instances working with EFA. Those can't automatically get a public IP so we need another way to give them internet access e.g. via NAT.
