Ability to migrate to a dual-stack cluster

[tearfulDalvik]

Is your feature request related to a problem? Please describe.

The default is ipv4 single stack cluster. I wonder, without changing the exisiting ipv4 podcidr, if there's a way to add ipv6 block to podcidr in order to migrate to a dual-stack cluster

Describe the solution you'd like
A solution like editing the /etc/rancher/rke2/config.yaml, and restart rke2-server

Currently, there is no way to do this. The first component that should allow this is the CNI plugin and, as far as I know, neither Calico nor Cilium support it
